Producer Giancarlo Volpe has hinted the next two episodes for Green Lantern: The Animated Series were thought of as a two part story much like the debut two part "Beware My Power" episode. So prepare for something epic! Here's the official description of the episode as well as two preview clips and some new official promotional images provided by Warner Brothers.
The heroes attend a rebuilding ceremony between the Guardians and the Red Lanterns on their capitol planet, Ysmault.
