The leader of the Temple of the Triune, the Primus was, for awhile, Lucion, the son of Mephisto. After a conflict with Uldyssian and also slaying the master markssman Achilios, he becomes nothing (which is how a demon truly dies). With no one to assume the role as master of the Temple of the Triune, Lucion's insane sister, Lilith takes on the guise of the Primus and decieves numerous followers of the Temple, like they have been being decieved for years.
