One and a half thousand years ago, on the planet Teknor, the race of Avems (bird people) exterminated the Lakerts (lizard people). But the son of the monarch, Lord Castor, helped the surviving Lakerts create a portal and escape to another planet. And now brother and sister Angel and Kira Wood accidentally activated the portal and ended up on the planet of the Lakerts, where they were met by the same Lord Castor. Lord Castor, who turned out to be immortal, longs for death, and the Lakert race wants to take revenge on the Avem and reclaim Teknor.
