Orphans

The Orphans are characters in Marrow.

Description
The orphans are a set of thirteen children whose spirits were stolen away by Familiar. Marrow starts with Daniel awakening in the Old Mountain Home to find all of the Orphans missing and a hole in the bottom of the manor. There, Daniels ascends into the corrupted world of Marrow in order to rescue the Orphans. All thirteen Orphans must be rescued before the player can access the good ending of Marrow. Should the player not rescue all the Orphans, they will instantly die upon defeating Familiar.
