Cry Havoc

Cry Havoc is the thirteenth episode of Tenko and the Guardians of the Magic.

Synopsis
Vell joins forces with Jana to steal Tenko's piece of the emerald Starfire Gem, and takes it from her after trapping her in a volcano. Tenko follows them to the ruins of Atlantis, where Vell betrays Jana and uses her life-energy and the emerald to try to free an ancient demon. Jana combines her power with Tenko's to seal the demon away, but doesn't know when to stop and tries to take the emerald even when the cave starts to collapse, burying her. As Jason arrives at the mouth of the cave, an eerie green glow is seen coming from within.
