"She was born in a place not remembered in a time long ago. It was not her life before that mattered, but what she became. When she entered the Lost Tomb of Setesh and offered unto him her devotion. This was when she was truly born." --- Herald of the Nightless Court
Arida the Desert Lich discovers the lost tomb of the God Setesh and with her devotion revives him from his imprisonment, lost and forgotten to his followers. He granted to her his knowledge and power and in return she is his immortal servant, tasked with being his hand.
