Before Garth's birth, his parents, King Thar and Queen Berra, became the reigning monarchs of Shayeris, the capital of The Hidden Valley of colonies. Thar had inherited the throne and access to ancient magical energies that his brother Zath, a powerful magician in his own right, believed to be rightfully his. Zath practiced dark sorcery and necromancy and was eventually banished from the Hidden Valley. His body transformed into a disgusting half-human form, Zath, renamed Slizzath, returned to Shayeris twenty years later with an army of undead. He planned to invade the Hidden Valley and transform it into a necropolis he would rule.
