Park is an Imugi that has yet to become a Yong(Korean Dragons). He's fairly quiet, doesn't speak out as much as he should, but is quick to think of solutions for problems at any given moment. Park is basically the runt of the liter in his family due to the fact that he hasn't become a Yong like the rest of them. Most of his siblings found him to be a burden, but the few others were more patient and understanding. They taught Park martial skill and an elemental art called Aero Arts, which allows him to manipulate wind. Park and his siblings were given the task of watching over the manor while their mother and father went to fight the demon lords that were wreaking havoc upon the mortals realms. Unfortunately their parents didn't return, and they were presumed dead. The eldest and ruthless of the siblings took the opportunity to claim the title of Lord of the manor for himself, and he also cast out the weakest siblings, which was of course Park. A few months pass with limited knowledge on how to survive out on his own and occasional help for the small handful of siblings that still cared for him, Park runs into Jack and Irene's band of travelers, becoming their 9th member.
