Thrull

Created by the Fleshmages of the Orzhov Syndicate using the bodies leftover from their debtors once theirs souls are collected, these small, impish, and gray-skinned humanoids are created solely to serve and have almost no personality or ability to function in a capacity beyond that.
Not all thrulls are small and the degree of their service depends on what they are designed for. Some large thrulls are even used as transport for the Syndicates favored.
