Doomguard

The Doomguard is one of the "official" philosophical and political Factions of Sigil. They are nicknamed "Sinkers". Their belief is that the decay and entropy of everything is not only inevitable but a good thing, and what is supposed to happen. Though they do not generally act to wantonly destroy everything they come across, they are in favour of the ideas of entropy and chaos and may well be disposed to help them along in ways they see as suitable. They are also not likely to worry much about the cessation, decay or destruction of anything, since that would be against their tenets. They find common ground with the Bleak Cabal, a faction that believes nothing has any meaning, and the Dustmen, who believe this life is nothing but a bleak afterlife to be transcended by reaching oblivion. On the other hand, the Doomguard is at odds with the Harmonium and the Fraternity of Order, two factions that place much importance on order.

The Doomguard have a tower called Citadel Alluvius on the Plane of Dust, where everything slowly disintegrates into dust.
