An old rosewood adventurer, disappeared into the wilds. And mysteriously returned.

Kiruko might be a legend to some adventurers but their existance is indeed confirmed. They were one of the earlier adventurers in Rosewood mysteriously dissappearing like most but suddenly turning back up during the ambush of 8th of Saga in year 7.
 
One of the most interesting myths that surrounds Kiruko is the fact that they seemingly abandoned their hearthstone. Having never even used it once. They supposedly wielded clerical and almost divine powers.
