Sisters
Somehow, in my characters' elaborate backstories, they all end up to be family members. Here, we see Cynnosure, holy warrior, posing with her younger sister Checkers, who has recently embraced the light. These two holy warriors are nothing if not pragmatic -- Cynnosure saw Checkers' time spent studying the shadow as only sensible.
Cynnthia & Felicia have a somewhat more complicated relationship, as they had very different reactions to the death of their parents to the Scourge. Cynnthia chose to confront her anger head on, with a sword. Felicia has adopted the dark magics that brought the undead into existence -- she says, to better combat them. Neither really understands or respects the other's decision, but they still try to make it work.
Cynndethiel Stormwalker had a sister, once. Dechesel was lost in the fighting when the Burning Legion invaded Ashenvale, and was presumed dead.
Imagine, then, Cynne's surprise when the Knights of the Ebon Hold renounced the Scourge - and Dechs was among the undead Death Knights now returning to the Alliance, and renewing old ties.
