Tieflings

Native to the continent of Caldresia, Tieflings are a rare race of people. Their true origin is unknown, with some believing they are direct creations of the Deity Mephistopheles while others estimate they migrated from the fiery lands of Kaldor's Spine. Tieflings record their cultural history through oral traditions and by literally weaving important events into the fabrics of the clothes they wear.
