Strange old house

The Strange old house is a place in the Sanctuary, where you deliver the lost souls discovered in your run through the levels. The only resident here is an enigmatic man seated in a couch who says to be the reaper. This NPC gives the player a stone used to catch the lost souls, and request to him or her to gather those souls in exchange to open a certain level of the catacombs, where the player can acquire experience and items.
