The title “Cult of the Dragon Below” is a blanket term used to describe any sect that serves a malevolent power or has bizarre beliefs that defy rational thought. But no member of such an organization would call themselves a “cultist of the Dragon Below.” As a true believer, you might be a blessed eye of the All-Seer, a pilgrim on the road to the Inner Sun, or a warlock in the court of the Queen of Shadows. If you’re a member of one of these three cults, you don’t see the other two as allies, for they’re clearly dangerous and delusional. And while outsiders may be able to guess what force is behind the cult—it doesn’t take a Korranberg sage to guess that the people growing eyes on their hands might be tied to Belashyrra—only a fraction of the cults of the Dragon Below knowingly serve a daelkyr or overlord.
Cults of the Dragon Below are categorized by two elements: structure and power. The structure defines the shape and scale of a cult, while the power is the malevolent force behind it, usually a daelkyr or fiendish overlord. The cults of the Dragon Below table provides a few examples of cults—simply scratching the surface of what can appear in the world—and the rest of the section explores these elements in more detail.
Cult Structure
Rak Tulkhesh has tribes of barbarians clamoring to spill blood in his name in the Demon Wastes. He has loyalists in the Five Nations subtly spreading hatred and ignorance. And he produces revenants, innocents who wake up convinced they are reincarnated soldiers with a duty to complete unfinished battles. This is common—most overlords and daelkyr have multiple cults, each completely unaware of another. While each cult is unique, most fall into one of the following three categories.
Corrupted
Members of these cults are united by shared delusions, the reality of their minds corrupted by a horrifying alien force. Sometimes the delusion infects those who take part in the rituals; other times the ideas first leak into people’s minds, then draw them to the cult. This is why the cults of the Dragon Below can never be wiped out, and why they can appear anywhere— you never know when or where an irrational idea can take root, twisting the thoughts and beliefs of innocent people.
While a corrupted cult’s beliefs and actions may seem irrational to outsiders, to members of the cult they make perfect sense. A revenant truly believes they are a legendary hero reincarnated. A Vigilant Eye cultist believes they’ve been given blessed vision that reveals evildoers who must die. The fact the cultist has grown a new eye doesn’t seem strange to them—it’s a blessed eye! Others are just jealous they don’t have one. Corrupted cultists may see the world differently than people around them. A group of revenants could be working with a mind flayer and dolgrims, but they see these aberrations as loyal knights tied to their ancient order. When encountering a corrupted cult, player characters will face the challenge of making sense of the delusion—understanding what the cult members believe they’re trying to accomplish, and how it relates to what they’re actually doing. These delusions have nothing to do with mental illness and cannot be treated at a Jorasco healing house. This is a form of supernatural influence with a specific cause—a corrupting alien entity—and with a specific effect; corruption can take hold of anyone at any time, and cultists may otherwise appear perfectly healthy and sane.
Corrupted cults rarely last long. They typically come into existence with a clear purpose, a specific scheme that somehow benefits their guiding power. After this scheme succeeds or fails, the driving force often abandons the survivors. The question is whether this releases cultists from the delusion, or whether they are simply abandoned—or even driven toward destructive acts. A second important question is whether it’s possible to free a cultist from their delusion while the cult is still active. This could require magic, such as greater restoration. But it could simply require the cultist to be isolated from their allies and deprogrammed, or perhaps separated from an item that is reinforcing the delusion. If this powerful delusion can be broken, perhaps the cultist’s original identity can reassert itself.
The power behind a corrupted cult isn’t always obvious. Loyalists know the power they serve and often proudly proclaim it, but many other corrupted cults aren’t aware of the power behind them. Vigilant Eye cultists could mistakenly believe that their blessed eyes are a gift from Aureon, while a revenant might believe Dol Arrah has returned them to the world. Even if the cultists themselves don’t realize who they serve, the trappings can be a giveaway. Belashyrra’s cultists often deal with eyes or beholders, Dyrrn employs illithids and doppelgangers, and Kyrzin’s cults usually have something to do with oozes and slime. But sometimes a cult can appear perfectly innocent. Are you absolutely certain that revenant wasn’t restored by Dol Arrah?
Traditional
There are cults far older than any human civilization. Their strongholds are in desolate regions—the Demon Wastes, the Shadow Marches—but immigrants have carried these beliefs into the Five Nations. The members of these cults have been raised to believe that the traditions of their faith are normal. You remember when your grandmother was consumed by the gibbering mouther in the basement. What’s wrong with that? It was her time and her passage to immortality; you’ve heard her speaking to you in the whispers of the mouther. You hope that you’ll live long enough to join her in its bowels.
Traditional cultists are typically less volatile and extreme than corrupted cultists; surviving long enough to become a tradition means avoiding reckless behavior and learning to keep your faith hidden from strangers. Many traditional cults can seem harmless; for the most part, Whisperers have no interest in harming or interacting with outsiders. However, traditional cults provide a lurking support network that can be activated when needed. Rak Tulkhesh has loyalists hidden throughout the armies of the Five Nations, always ready to escalate violent situations. And a town could be filled with followers of the Transcendent Flesh who appear completely harmless and mundane—until the Night of Six Moons, when they all attach their symbionts and tear apart any outsiders unlucky enough to be in the town that night.
Traditional cults are less extreme than corrupted ones, but they still see the world through a strange lens, despite knowing the power they’re bound to. Some traditional cults believe their patrons are simply misunderstood—Dyrrn seeks to elevate humanity, not to corrupt it! Others celebrate the destructive or chaotic aspects of their patrons, either believing that this corrupt world deserves to be torn down, or that the faithful will be elevated in the next age. Even a cultist who reveres Rak Tulkhesh may not be evil; they could believe the corrupt world must be washed in blood to cleanse evil, and aside from their duties to the Orphan King, they may be gentle and altruistic.
Transactional
The dark powers associated with the cults of the Dragon Below have much to offer. They can imbue their servants with mystical powers, following the model of the warlock. Daelkyr can provide symbionts and physical transformation, while the Lords of Dust can provide wealth, influence, or ancient artifacts to their loyal agents. As a result, transactional cults often begin as secret societies. People join of their own free will, eager to obtain whatever it is the cult has to offer. But even if someone joins for the most rational of reasons, the influence of a daelkyr or an overlord is difficult to resist; the longer someone remains in the cult, the more power it will have over them.
Consider the Court of Shadows cult, tied to Sul Khatesh. A wizard has a fascinating conversation with a colleague, discussing a spell unlike anything they’ve seen before. The colleague explains that the spell is from Ashtakala’s vaults, and if the wizard joins the Court, they’ll discover many amazing things about magic and history. So they go to a meeting and are impressed by the scholars and warlocks they meet. Soon they’re initiated into the cult, swearing an oath to the Queen of Shadows and being invested as the Knight of the Forgotten Library. It seems like a game, and they’re gaining access to fascinating new spells. But as time passes, they become ever more obsessed with rising in the Court of Shadows. The political interplay in the Kingdom of Shadows feels more real, more relevant than the mundane politics of Khorvaire. They pursue missions for the Queen, yearning to win her favor. And they hope that someday the Queen will rise from her slumber, for then, the Kingdom of Shadows will truly become real.
Transactional cults can be found anywhere on this slippery slope. A transactional cult might use symbiont weapons but otherwise be quite rational. Or, while you can still see how they stumbled into this mess, they could be completely pulled into the warped reality espoused by the cult.
Transactional cults are typically small, but can be widespread. A coven of the Court of Shadows may only have a few members, but the Court itself is spread across Khorvaire. Often, members of transactional cults know who they are dealing with, but greed or curiosity overrides concerns. However, it’s also possible for people to only know part of the story; a warlock might believe that the Queen of Shadows is a mighty warlock or perhaps an archfey, not realizing she’s actually an overlord.
Cult Goals
What do the cults of the Dragon Below want? What do members strive to achieve? This varies based on the structure and patron of the cult. All of the malevolent powers described in this section have loyalists, cults that are devoted to releasing their lords from Khyber or helping their agents (be they Lords of Dust, mind flayers, or rogue dragons) with whatever they require. But beyond the loyalists, cult goals can be a little more exotic.
Corrupted cults usually have some sort of immediate goal that drives the formation and expansion of the cult. The Vigilant Eye is hunting down “demons” hidden in the community, which can only be seen with their blessed eyes! The revenants have to re-enact a brutal massacre that occurred five hundred years ago today! The goals are often terrible things that must be stopped, but it’s not always obvious how they are helping the power behind the cult; these schemes may have nothing to do with the seals of the daelkyr or releasing an overlord. In the case of an overlord, the archfiends gain strength by driving mortals down their paths. For Sul Khatesh, getting mortals to use magic for malevolent strengthens her regardless of what they actually do; likewise, Rak Tulkhesh revels in all violence. Meanwhile, the daelkyr are truly incomprehensible. They certainly enjoy experimenting with their preferred mediums; one of Dyrrn’s cults could enact a ritual that causes dragonmarks to come to life and attack their bearers, with no purpose beyond satisfying Dyrrn’s curiosity. As the daelkyr experience time in a nonlinear fashion, it’s also possible that what seems like meaningless chaos could have a unforeseen future—that there will come a time when a living dragonmark unleashed in the cult’s bizarre rampage ends up being the vital element needed to defeat one of the Lords of Dust. The key point is that cults of the Dragon Below—particularly corrupted cults—may not have long-term plans; their schemes can and should often appear nonsensical.
Traditional cults are religions. They aren’t driven by short term goals, but instead provide guidelines on how to live your whole life. Traditional cults can be peaceful and innocuous . . . until they aren’t. A particular alignment of moons, a vision sent to the cult leader, a critical mass of outsiders arriving at the same time—any cult could have a set of circumstances that trigger bloody rituals or brutal sacrifices. This is where the absurdity of a traditional cult rises to the surface. The people of Lowholt couldn’t be kinder—until the flesh barn runs low on spleen and they have to harvest your organs. It’s a real shame, stranger, but our grandparents have to have that spleen—the “grandparents” in this case being the gibbering mouther in the basement.
Transactional cults are often initially driven by the desires of the members. Someone joins a transactional cult because they want the power to do something—to take revenge on their enemies, to overthrow a tyrant, to destroy a local criminal gang. But the patron always has a price, and this can eventually follow the same model described for corrupted cults earlier.
The Powers Behind the Cults
Each cult of the Dragon Below is tied to a sinister power trapped in Khyber, and a cult’s goals usually reflect the power behind it. If the cult has inhuman allies, are they fiends, aberrations, or other monsters? What sort of treasures and magic items does the group use? These magic items aren’t necessarily direct gifts from the patron; a cult of Kyrzin may have many potions because the high priest is an alchemist, or because a strange fountain in the temple secretes mystical fluids. In the case of loyalists and traditional cults, the connection to its patron may be quite obvious, whereas corrupted cults can be challenging to identify the hidden manipulator. Regardless of whether cultists know the identity of their patron, the power behind a cult has many effects.
As a broad rule, cults tied to overlords (Rak Tulkhesh, Sul Khatesh, Katashka, Bel Shalor, the Daughter of Khyber) are either directly helping the Lords of Dust or trying to drive behavior that strengthens the archfiend. The daelkyr (Belashyrra, Dyrrn, Kyrzin, Orlaask, Valaara) are more enigmatic. Their traditional cults may continue strange patterns of behavior handed down for generations, performing sacrifices or mysterious rituals when the planes are aligned. But they can also engage in dramatic actions with no clear benefit to anyone. There’s no clear reason for Orlassk to turn citizens of Sharn into gargoyles; it could be an experiment, or simply a form of art. But these actions will be related to the sphere of the daelkyr that causes it, whether that’s oozes, stone, eyes, or insects.
