At the date 3/16/10702 Fadoran became the patron of Jen, and he gave her a piece of Kal'Thozul's bones. Fadoran helped turn Jen into a Banshee and gave her her Witch powers and a Dark Grimoire. She started her own army, the Forsaken, but still follows Fadoran and Rhowar as a member of the Order.

Gurshy used to temporarily be a part of the Order at invite of Jen, but since his death, he joined Covenant instead. He also still accompanies Jen as a member of the Forsaken, though he's not really that recognizable anymore.
