Undead, Lycanthropes and other Misplaced Essences
Every living person carries within them something that makes them who they are — the animating principle that takes oaths, holds obligations, and belongs in the world. In Oath-Bound this is commonly called the Essence. Under ordinary circumstances it arrives with birth and departs with death, and its departure is final. What remains after is a body, not a person.
Some things in the world represent a failure of that ordinary process. The body persists without the essence, or the essence persists when it should not, or the essence is present but wrongly situated. These conditions produce different kinds of problem, and divine actors are specifically equipped to address them.
Low Undead — The Essence Gone
Low undead are animated bodies from which the essence has departed. Skeletons, zombies, and their kind are not people. They are not the persons they once were, retaining some remnant of identity or will. The essence is gone. What moves is the body, driven by whatever force set it in motion.
This is why divine actors can exert control over low undead directly. A creature with no essence has no personal relationship to the oath economy, no will to negotiate with, no standing in the world that commands respect. The divine authority a Foundation priest carries applies to it cleanly and without complication. Turning low undead is a straightforward application of that authority — the priest does not persuade or overpower, they simply assert a claim the creature has no capacity to resist.
High Undead — The Essence Wrongly Present
High undead are a different matter. A vampire, a lich, a wight — these retain their essence. They are still, in some meaningful sense, persons. The essence that should have departed at death is still present on the prime material plane, wrongly, and that wrong persistence is precisely what makes them dangerous. They can think, plan, act with purpose, and in some cases exercise the kind of will that makes direct control impossible.
Divine actors do not turn high undead the way they turn low undead. The techniques available to them are more specific, more demanding, and require a clearer understanding of what they are dealing with. High undead are addressed rather than simply commanded.
The details of those techniques belong to the GM-facing material and to what a divine actor learns through their Foundation training. What a player should understand is that the wrong persistence of a high undead’s essence is a theological problem as much as a practical one, and that their divine actor is specifically trained to recognize and respond to it.
Lycanthropes — The Essence Displaced
Lycanthropy is a third condition. The essence is present — the person is still there — but it has been wrongly repositioned within their living situation. A lycanthrope is not dead. They are not empty. They are a person whose essence has been displaced in a way that compromises their relationship to the oath economy and to their own will.
Divine actors have specific capabilities with respect to lycanthropes that follow from this framework. The essence is present and reachable, which creates different possibilities than the empty body of a low undead or the wrongly persistent essence of a high undead. Again, the specifics belong to Foundation training and GM-facing material.
What This Means in Play
Players running divine actors should understand that their character’s capabilities in this area are not simply "turning undead" in the vanilla AD&D sense. They are a coherent set of responses to a coherent problem: essences that are absent, wrongly present, or wrongly situated. The framework shapes what a divine actor can do and how they think about what they are encountering.
Players running other actor types should understand that these creatures are not symmetrical threats. A low undead and a high undead in the same room are not the same kind of problem at different power levels. They are categorically different, and what works on one may not work on the other.
