Die Vecna Die! synopsis:

Vecna breaks free of the demiplane of dread and enters sigil after devouring Iuz and his divine ranks.

(This is done through a set of events set in motion years ago by Vecnas worshippers in Sigil:
Ely Cromlich - High priest of Vecna uses the chaos of the faction war to assassinate key elements 
in the signers ranks, allowing the cultists of vecna within to subvert the think tanks placing
the divinity of vecna within the linqua omott instead of the planned aoskar.

Vecna and ely are destroyed by a group of heros. The lady lifts the ban on the faction and appeals
to the ciphers to restore order to the city.

This, only happens after a certain fated ahmed imposes law through political dealings with some other
factions and sects.
