Saturdays of Slaughter
Little is known about the Triangle. They were first encountered when a group of dopplegangers infiltrated the town as the Steel Regent and body guards. They were quickly found out by the Knights and dispatched for being impostors. They wanted to get to get into the city to claim the power for themselves.
Rillindy, a halfling from Daggerdale, is a known contact of the organization. He was the one that hired and sent the dopplegangers into Tilverton. The party tracked down the halfling and forced him to tell his secrets of what he was doing for the triangle. He was creating a portal to the Fugue Plane in order to release Dendar the Night Serpent. He claimed to not know the name of his contact, but upon examination of his papers Morani Stoutsmasher from White Crag Tower was fingered as a known associate of the Triangle.
The party took out Morani Stoutsmasher and her evil cronies in the White Crag Tower. Her death only revealed that this was a larger organization.
The party found out that a Lich had Sir Marren’s wife. Using some planing the party infiltrated deep into his stronghold near Selgaunt before the lich could even begin to mount a defense.
The doppleganger also revealed that someone in town was passing information, though she didn’t know who it was.
