Life, Death
The anarchists kill the leader of the mercykillers.
The Revolutionary League murders the factol of the Mercykillers, spawning a war that eventually embroils a full dozen factions, and resulting in the dissolution of the Incanterium, the Zactar, and the Ochlocrats. The Harmonium, having been waiting for such an opportunity, move into Sigil, quickly filling one of these new-found gaps to become one of the city's 15 factions. The Athar take this chance to return as well, once more taking possession of the Shattered Temple from the vagrants and barmies that had been calling kip there.
