Sampo is an eloquent mercenary from the Underworld who does all sorts of jobs for his "customers," as long as he doesn't get paid off with a higher price. Despite his seemingly easygoing nature, Sampo's background is shrouded in mystery with no one really knowing where he came from or his past dealings. Sampo had caused a lot of trouble in Belobog and is the only one who can seemingly traverse from its Overworld to its Underworld before the events that lead to its reconnection.
