He was born in the "lost world" of Skartaris. As an infant, Joshua was stolen from his parents by the evil sorcerer Deimos where he was raised to fight against and betray his own father. Instead, when Warlord came to collect his child from Deimos, Deimos cloned young Joshua. He rapidly aged the clone and forced it to fight Warlord to the death. Believing he had murdered his own child, Warlord was completely heartbroken. Secretly, however, the witch Ashiya gave the child to a kindly farming family. When his adoptive parents were killed, he came to Shamballah and became an ally of the Warlord anyway.
