The Advanced Dungeons and Dragons supplement, Oriental Adventures, gave Dungeon Masters the tools for creating an Eastern themed medieval fantasy world for their Players to explore. This book introduced several new races and classes, which includes the Korobokuru; an Eastern variation of the Dwarf. The Korobokuru (also spelled as Koropokuru or Koropokguru) are based on a mythical race of humanoids from Ainu folklore.
