Dar, the son of a king, is hunted by a priest after his birth and grows up in another family. When he becomes a grown man, his new father is murdered by savages and he discovers that he has the ability to communicate with animals, which leads him on a quest for revenge against his father's killers.

The Beastmaster Dar is forced to travel to earth to stop his evil brother from stealing an atomic bomb, and turning their native land from a desert into... well... a desert!

BeastMaster chronicles the adventures of Dar, the last surviving male of the storied Sula tribe, who is blessed with the ability to communicate telepathically with the animals of his ancient world. Also endowed with the strength, courage and fighting skills of a great warrior, he uses his gifts to defend all living creatures oppressed by the forces of evil.
