In the 24th century a dying Earth sends out twelve brave starships to repopulate distant worlds. Each ship contains over five hundred 'colonists' and a legion of Deep Space Marines. When Transport Starship #7, The U.F.S. Hector, lands on Beta Seven they find their lush, new Eden-like planet already populated with exotic wildlife, primitive tribes of beautiful wood-nymphs or 'Elves' and a large, savage, medieval race of conquering nomads. The 'colonists' only hope is that the Seventh Legion of Deep Space Marines can carve out a truce with the fierce and cruel Volta.
