Angkor and Yo-Yo are two of my characters from LOFP -which doesn’t stand for anything important - a story similar to CK in that it is very old and shared with a friend. I have a different conspirator for this universe, though.
Angkor is the single distillation of ‘dark’ among his race of elemental phoenix people, and Yo-Yo is a girl who became obsessed with him. She collected a few of his feathers innocently enough, but her obsession with Angkor fused them to her body and corrupted her. Yo-Yo uses powerful magic, with Angkor’s feather’s amplifying her natural capacity.
