Sect of Faces
One Outsider lord of the Nameless Court manifests via an ever-shifting identity known as the Lady of Faces. The cult that worships the Lady consists of spies, assassins, and diplomats who are not what they seem to be. They have wormed their way into the ranks of courtesans, advisors, sages, clerks, and aristocrats surrounding powerful nobles. Some even believe these nobles are members of the cult as well.
Each cultist has multiple hidden identities, like the skins of an onion, with their true self (if one exists) buried deep inside. No one knows what the true goal of the Sect of Faces is, but it seems that whatever it is attempting to do, it must gain or control a great deal of political power and wealth to enact it. Purportedly, those at the center of the cult have no identity at all and can shift their appearance at will to look like any humanoid creature or person. All recruited to the cult bear a version of the Symbol of the Nameless Court in bright amber and identify themselves as loyal by telling other members, “I wear no mask.”
