The Tribunal manage the Adventurers of the world. It's actually in the helpfile "help law"

"""*** The areas that are defined as protected by the jurisdiction of the Law
are the entirety of Galadon, Hamsah Mu'tazz, Voralian City, and Seantryn
Modan. With the exception of the fifth law, the cities police their own
denizens, leaving the Blood Tribunal to focus on the actions of
Adventurers and their servants."""

There is a difference between denizens = NPC's of the cities, and the
Adventurers of the realms = Actual players of the world.
