It started off as a pleasant enough day in the City of Doors. The gnome went off to purchase a helm for his tiny little head, the halfling went to see her lover, the kender headed off towards the Civic Festhall to report, the tiefling attempted to frame the gnome for theft, the gnome was scragged for putting some poor shopkeep in the dead-book, and the dragonborn was hired to watch the scene of the crime while the tiefling and kender got piss drunk.
And somehow, the entire lot of them just gave the Cage the laugh.
Then the Faction War happened, and the Lady of Pain herself (or at least through the Dabus) gave the ultimatum and the surviving factions either fled Sigil or simply disbanded.
A Few Years Later . . .
It was an ordinary day in the City of Doors, and just like on every other day, a new group of clueless arrived, and judging by the state of their gear, they came from the Feywild.
Then it happened.
Something that has never happened before in Sigil, something that the Lady has never allowed.
The avatar of a god tread through a tear in the sky and into the Cage. He very quickly set up shop in the remains of the Armory, shaping it to suit his purposes. He was followed by some addle-coved out-of-town elf who quickly joined up with the group of barmies who decided it might be a good idea to follow the god.
Somehow this group got lucky, as they not only came to the attention of the Lady of Pain, but they survived her wrath and left to follow the power, who is called Vecna, I think, into the Armory.
They quickly dispatched those Doomguard who had fallen in the Faction War, and barely survived battling with the Slaadi who had claimed the Armory as their own before the Whispered One even came into the Cage. After a battle with more of the lost bashers who died for their faction, they tracked the Maimed God down into a new under level of the Armory loosing one of their own in the process.
For the sake of the Multiverse, I hope they succeed and defeat the Master of the Spider Throne.
