From publisher blurb:
This Demi-God race is provided for those seeking to run a campaign inspired by the struggles of demi-gods to live among mortals. Such are the tales of the Greek demi-gods from the Heroic Age, of the Iliad and Odyssey; of the descendents of Odin among the early Migration Era tales of the Germans and early Vikings; or the tales and legends of the great heroes of India such as the Mahabharata.
Note that the abilities of the demi-god are mostly balanced out by the fact that her divine parent's enemies, inherited along with her abilities, will often seek her out to destroy her or seduce her to their side. It should also only be used in a campaign where the Labyrinth Lord has the players roll 3d6 for ability scores, limiting accessibility to races appropriately.
