"Last Kill!"
*Raven is aghast as the horrors perpetrated by Trigon on his homeworld and learns that he has no intention of abandoning his invasion of Earth despite his promise to her. While the disciples of Temple Azarath refuse to aid the Titans in their battle against Trigon, they do transport the super-heroes to Trigon's world to battle him anew. The Titans are again easily bested by the demon but Arella, Raven's mother, helps her to escape Trigon's influence and to free her teammates. By combining their magical and scientific powers, the Titans are able to banish Trigon through a dimensional doorway. Arella then sacrifices herself to become the eternal guardian of the gateway to prevent Trigon from ever escaping again. *Source: Official Teen Titans Index #3 - Published by ICG
