The titular members of the Wolf Alps.
Before he was the bi-polar, PTSD riddled cynical drug addict Ereso Ciau was the shy and quiet newbie that would show up with weird bruises that he wouldn't talk about.
Albrecht Ondulv is the alp born prodigal son and heir to the Wolf Alp Clan. He was Ereso's best friend and taught him a ton of tricks that came with being an alp.
Klaudia von Brooke, also known as Klaudia the Cute (mostly by Albrecht, and by Ereso when she's not looking) was Albrecht's second in command and lover. Klaudia was abandoned as a baby by a brook and found and raised by the Wolf Alps.
And Til the Wolf Alp, the leader and founder of the Wolf Alp Clan. An incredibly powerful and ancient alp nearly 2,000 years in age that always remains in the form of a wolf.
