You’ve heard of the Basilisk’s Gaze, then? Medani operatives, charged under the Treaty of Thronehold to hunt down the worst war criminals of the last century. It’s kind of odd, right? If you want to FIND someone, you go to Tharashk. Why Medani? Well, it could be that Breland objected to Tharashk because of their close ties to Droaam. But you know what I think? I think it’s because these people the Gaze is hunting, they aren’t common criminals. They’ve got money, influence, magic. These people can shield themselves from divination, establish new identities. Finding a person like that, it’s more of a puzzle than a job for a simple bounty hunter. And apprehending them… that’s a thing that would have to be done quietly and carefully. You’d have to be able to anticipate their routine, know where they’d start their day. Know their favorite strain of tal. Have a paralytic poison on hand, slow-acting but undetectable, and have sufficient charm to keep them talking until the poison takes effect. What do you think? Hmm? Can’t respond? Don’t worry. My friends and I will help you out. You’ve got a tribunal waiting for you at Thronehold, Viktor ir’Cazin.

The Mark of Detection enhances the bearer’s Insight and Investigation. This isn’t about broadly improving eyesight or hearing. Instead, Medani intuition calls attention to details. A marked Medani is always noticing things about their surroundings others might ignore. When talking to someone, a Medani instinctively catalogues their twitches and tells, evaluates their accent and how it aligns with their supposed nationality, observes their equipment and its quality… and does all of this without even thinking about it. But when the details matter, all of these observations will come flooding back. The greater powers of the Mark of Detection go beyond personal observation. While some within Medani say that their house is blessed by Aureon, the dominant belief is that the Mark of Detection connects everyone that carries it, and that a Medani with a powerful mark can draw on the memories and observations of every marked scion of the house. Because of this, the house strives to constantly expand its knowledge base. In many of the Dragonmarked Houses, heirs of a house are often raised in house enclaves and educated in trade schools tied to their guilds. By contrast, House Medani encourages its heirs to be active in local communities and to cultivate a diverse group of friends. Before undergoing the Test of Siberys, a Medani heir must complete an apprenticeship outside of the house. The point of this isn’t to pursue a long-term profession, but to meet people and to make connections… to learn seemingly inconsequential details that could be of use to some other heir of the house at some point in the future. In addition to the Watchers of the Warning Guild, House Medani maintains a corps of “Private Eyes”—Inquisitives tasked to travel across the world and learn things, unraveling mysteries when they find them and pulling on interesting threads. This is a possible path for a Medani adventurer. Watchers of the Warning Guild typically work out of a particular office in a particular town. But Private Eyes are encouraged to keep moving, searching for the most interesting situations and people that they can find. As a Medani heir, ask questions and explore even tiny mysteries. Even if the answers to your questions don’t have an impact today, they could help your family in the future!  

Perception or Investigation? In Rising From The Last War, the Deductive Reasoning feature of the Mark of Detection provides a bonus to Investigation and Insight. However, in the recent Unearthed Arcana, the Mark of Detection feat provides a bonus to Perception and Insight. These are the same two skills that are boosted by the Mark of Sentinel, and in my opinion, Rising’s approach makes more sense. Sentinel helps you spot the immediate threat with Perception; Detection helps you examine the scene and draw conclusions. We don’t yet know what the final text of Forge of the Artificer will be. For now, the DM will have to decide what they want to do. But in MY campaign, I’m keeping Detection as benefitting Investigation and Insight.

The Mark of Deduction

Beyond an intuitive knack for Investigation and Insight, anyone who carries the Mark of Detection can cast Detect Magic and Detect Poison and Disease. Because they always have these spells prepared, they can cast them as rituals. But producing a spell-like effect through a dragonmark isn’t the same process as casting a spell. When performing the ritual to cast Detect Magic, a Medani heir doesn’t invoke words of power. Instead, most use one finger to trace the design of the Mark of Detection on a palm while murmuring observations about the room they’re in—temperature, sound, contents, meditating on each detail until their senses reach beyond the physical and they can feel the flow of supernatural energies around them. If you have the Mark of Detection, that’s just something you can do. Spend enough time contemplating your surroundings and you can sense supernatural energy. Other Spells of the Mark go beyond any sight or sense; they are about intuitive knowledge. An heir with the Lesser Mark can Identify magical objects. This is another spell that can be cast as a ritual, meaning that it’s something an heir with the Potent Dragonmark feat can simply do, provided they have time. If they take ten minutes to study an object, they know its magical properties. With the Lesser Mark they can study an individual and know what they are thinking. With the Lesser Dragonmark (meaning access to 4th level spells) they can simply ask a question and know the answer, by casting Divination. 

All of these gifts flow from the same source. While a Medani heir has to go through the same steps a spellcaster does to produce these effects—speaking and gesturing in some way—Medani’s Divination doesn’t feel like a priest calling upon divine guidance. Instead, to the Medani it feels like DEDUCTION. When they cast Identify, they take time to study the object—its weight, its composition, signs of wear, traces of arcane energy—and within ten minutes it becomes obvious what it does. When a Medani casts Detect Thoughts, they aren’t using telepathy as a Kalashtar would; they are simply observing, but through observation they deduce what the target is thinking. The verbal components of a Medani’s Detect Thoughts are questions; the Medani asks a few pointed questions, and draws conclusions from the most minute reactions. “Tell me, did you know Donal Gelder? Ahhh, you worked together, didn’t you? And you hated him.” Should the target succeed on their saving throw and resist the effect, the Medani can’t draw deeper conclusions about them. To be clear, this effect is magical. The Medani also has to provide somatic components—typically touching their dragonmark or tracing its pattern on a palm—and the mark does grow warm while they’re engaged in deduction. They can gain access to information that they couldn’t possibly deduce from available information. But to the Medani, and to observers, it feels like deduction—like they are leaping to certainty from minor details of a scene. 

Divination and Deductive Reasoning. Medani heirs with the Lesser Dragonmark often have the ability to cast Divination, and this is the hallmark of Medani’s master inquisitives. While the Augurs of the Voice of Aureon call this gift Divination, Medani inquisitives refer to it as Deductive Reasoning; they aren’t calling on a higher power, they’re evaluating a question and drawing conclusions. With this in mind, what exactly can Medani learn from using this spell? When performing Deductive Reasoning, the Medani draws on two potential sources of information. The first is the scene itself. Is there any possible way the Medani could deduce the answer from their surroundings, at least in part? Otherwise, the question is does any other Dragonmarked Medani know the answer to this question? So when a Medani inquisitive looks at a corpse, casts Deductive Reasoning (Divination) and says “Who killed this man?” the first question is if there’s a living Medani who actually knows the answer. If so, the inquisitive could just get that concrete answer; Alina Lorridan Lyrris poisoned him at dinner two hours ago. Assuming that’s not the case, think of all the greatest detectives you’ve seen in any form of media and the conclusions they might draw.  A strand of silver hair… a stray thread from a glamerweave gown… the placement and size of the chair… It was a wealthy female gnome. He knew her, and they were conversing when he died. See the faint scratches on the surface of the table? She was wearing rings, at least one on each finger. The point being that it’s not a randomly cryptic riddle—but it can still be a set of clues that point the inquisitive in the right direction rather than providing a concrete answer. Likewise, if the marked Medani asks a entirely abstract or philosophical question—What is the true nature of the Sovereigns—they’ll either receive no answer, or an answer that summarizes the dominant opinions of the Medani gestalt, with the clear note that it’s not a certainty. 

Legend Lore and Background Checks. Under the rules of 5th Edition, the Greater Dragonmark of Detection grants the ability to cast Legend Lore. But Legend Lore is an odd spell. 

Name or describe a person, place, or object. The spell brings to your mind a brief summary of the significant lore about the thing you named. The lore might consist of current tales, forgotten stories, or even secret lore that has never been widely known. If the thing you named isn’t of legendary importance, you gain no information. The more information you already have about the thing, the more precise and detailed the information you receive is.

The limitation that “If the thing you named isn’t of legendary importance” bothers me. Critically, who makes that determination? It also seems like an arbitrary limitation on a spell that is supposed to be the greatest power of the Dragonmark. With this in mind, in MY campaign, the Greater Dragonmark doesn’t allow you to cast Legend Lore; instead, it allows you to run a Background Check. Name or describe a person, place, or thing. The spell brings to mind a brief summary of lore about the thing you named based on what is known about them by living bearers of the Mark of Detection. Think of a gestalt consisting of both the conscious and subconscious memory of living Medani. Has any Medani ever seen the person you’re asking about? Do you already have information that could be combined with another Medani’s observations to draw a new conclusion? So like Legend Lore, the more information you already have, the more information you will receive; and likewise, if the individual or object is well known in the Five Nations, then Medani will know more. And again, this is the function of the Private Eyes—to gather as much random information as possible, which may mean nothing to the observer in the moment, but which can be added to the gestalt for Background Checks. So if you ask about someone who is truly unremarkable or about an obscure relic from tens of thousands of years ago, you might not get any information (although here again, the Voice of Aureon includes sages who study history, and their knowledge is part of the gestalt). But if you ask about a criminal, you might draw on the information of a Medani inquisitive who solved a previous crime they were involved in… and you might know that they were seen in Sharn a week ago. As always, it’s entirely up to the DM to decide what information is provided, and the bearer of the Mark can’t ask for clarification; they get the information they get. But even if we imagine a random commoner—let’s say Jurian Cooper—who’s definitely not LEGENDARY, a Medani Background Check might say Jurian Cooper is a male human in his thirties who’s been living in the Callestan district of Sharn for at least a decade. He has been seen in the company of Ilsa Boromar on multiple occasions. Last week he was seen in the Broken Mirror in Callestan, drinking Old Bender and eating a tribex pie. This also touches on the difference between the Mark of Finding and the Mark of Detection. A Background Check can’t tell you exactly where to find Jurian Cooper. But it may point you to known associates, recent haunts, or provide useful details you’re not going to get from Locate Creature. 

Nondetection. Everyone knows that the Mark of Detection lets its bearer uncover secrets. Fewer people know that it can help bury them, as well. The Wolves of the Warning Guild specialize in counterintelligence and in making problems go away. In doing so, they often employ the Lesser Mark’s gift of Nondetection—whether to conceal themselves, a client, or an inconvenient object (or body) until a case can be closed or a problem solved. This ability is especially prized by the hunters of the Basilisk’s Gaze, whose quarry often protect themselves with divination. This comes to a minor house rule. The 2024 rules have reduced the number of effects that say a creature cannot be surprised; notably, the Weapon of Warning no longer provides this benefit. But I personally say that if any magical source provides immunity to surprise (as opposed to a skill or mundane class feature) that the benefit will not help against someone who is shielded by Nondetection. Likewise, in my campaign Nondetection protects from magical effects that are clearly forms of divination even if they are not identified as being divination spells—notably, a Wand of Enemy Detection. 

Clairvoyance and Arcane Eye. These abilities are a form of extrasensory perception and have more in common with Detect Magic than Identify or Legend Lore. The heir concentrates on their Dragonmark and meditates on the location they wish to see, envisioning it in their mind… and soon finds that the vision in their mind is real and accurate. Sensors created by these spells appear as globes formed from stands of blue energy to those who can see them; sometimes the Mark of Detection appears within the globe, mimicking the iris of an eye. 

Detect Good and Evil? Good and Evil may feel like abstract concepts for an inquisitive to monitor. But keep in mind that Detect Good and Evil doesn’t actually detect alignment or morality. The spell effect is “For the duration, you sense the location of any Aberration, Celestial, Elemental, Fey, Fiend, or Undead within 30 feet of yourself. You also sense whether the Hallow spell is active there and, if so, where.” For the sensitive Medani, this isn’t much different from using Detect Magic to sense the flow of arcane energy. The Medani heir concentrates, extends their perceptions, and essentially finds what doesn’t belong, drawing on the Medani gestalt to further clarify the specific nature of the entity.

Dragonmarked NPCs 

In a previous article, I  discussed how I generally handle NPCs with dragonmarks. Here’s the key piece.

Potent Dragonmark is a feat designed for player characters. It’s flexible—allowing a character to access any spell on the Spells of the Mark list—and recharges after a short rest. But it sets the precedent that there are people in the world who have no spellcasting ability but who can still produce spell-like effects with Dragonmarks. With that in mind, I’d generally give dragonmarked NPCs a form of this, mirroring the original ECS marks. An NPC with a Least Dragonmark would be able to cast a 1st or 2nd level spell from their Dragonmark’s Spell of the Mark list, once per day. An NPC with the Lesser Mark would get a single use of a 3rd or 4th level spell, in addition to the Least Mark. And an NPC with a Greater Dragonmark would gain a single use of a 5th level Spell. Exceptional scions might have a choice of more than one spell at each level, just like a player character with Potent Dragonmark.

Now, as noted above, if a Spell of the Mark is a Ritual spell, then the bearer can cast it repeatedly as long as they have time to do so. But the key point I want to call out is that player characters get access to ALL the Spells of the Mark. Exceptional NPCs may as well. But most marked NPCs will have access to a subset of the Spells of the Mark, and this will often reflect their placement in the house. Members of the Basilisk’s Gaze are generally chosen because they have the ability to cast Nondetection and Detect Thoughts. Members of Aureon’s Voice are sure to have Divination and Identify. The point being that ALL Medani heirs have the ability to Detect Magic and Detect Poison & Disease, but even though it’s a power of the Least Mark of Detection, not every Medani heir can cast Identify. 

Focus Items. Medani heirs regularly employ the focus items described in Exploring Eberron—Dragonmark Channels and Reservoirs. Exploring Eberron notes the Medi Spectacles and Medi Dowser, dragonmark bound versions of Eyes of Minute Seeing and the Wand of Secrets. Here’s two more Medani focus items—one that’s useful for undercover operatives, another that helps the Inquisitive investigating a murder.

That’s all for now! This article is just a glimpse at the full House Medani article I wrote for my Patrons, which includes the history and structure of House Medani, as well as discussing its major enclaves and providing additional hooks for Medani characters and stories. This support is what allows me to take the times to write articles like this. You can become a patron here!
