Freedom of choice is an inherent part of all these outsiders as their status here is just another stepping stone in their evolution. As mortals the evolution is primarily symbolic and such, but once these mortal transition to outsiders they lose their access to their memories without losing their memories influence on their choices. At this point they begin a literal and physical evolution as they progress and develop. In theory as well (never had to deal with this quite yet) there are steps beyond outsider. Several of these will probably be me kidnapping stuff from the IH. At these further steps I will also reveal the big darks. Forces that wanted to do it all differently, and without freedom of choice. These forces will likely redefine evil, as their actions will always be large scale changes.
Hopefully I can keeping mining fluff for ideas while I steal critters.
