Infinite Consortium
The Infinite Consortium is a mercantile organization that spans several planes. It specializes in procuring all possible items clients ask for, even merchandise from other worlds. The Consortium was founded by Nicol Bolas and was taken over by Tezzeret sometime before the Conflux. The headquarters were located in the Iron Tower in a desert region of an unknown plane.
While the individual cells survived to some extend, the organization as a whole was dissolved, when Jace Beleren crushed Tezzeret's mind, destroying all the information needed to run the Consortium with him.
