I just got to the part in Prey Book 1 where they reveal that "Kruge", is actually Cross, a member of a group called The Circle of Jilaan that includes Ardra and a couple other people. I was just wondering if the Circle of Jilaan name or the other two members, Jilaan and Kerphestes, came from other stories? The way it's handled it feels like we're supposed to be familiar with the whole group, but Ardra is the part of it I'm familiar with.
