Faction within Sigil who believe everyone to be already dead. Handlers of the dead in Sigil.
The Dead have a job that suits them well, and one that nobody else is keen on anyway. In the Mortuary, they’re the ones who dispose of Sigil’s deceased. The Cage doesn’t have space for graveyards or crypts, so the bodies of her citizens get dispatched to other planes. These portals lead directly to mortuaries and other places of death on each plane, and those on the other side are expecting nothing but dead bodies to come through, so those cutters who somehow manage to sneak through any of these doors are in for a nasty bit when they pass through. The Dustmen handle all this work, and for the most part nobody minds. Then again, there’s always the suspicion that the faction’s keeping a few back and reviving them for its own purposes. . . .
