Hitrea was a planet full of harmony and lush landscapes, one where human beings and animals lived together in peace. Everything seemed perfect until three vengeful immortals appeared with the deep desire to unlock the legendary Chimera, an ancient beast of folklore said to be the most powerful creature in Hitrea. If the legendary Chimera is released, great destruction could come to Hitrea. Two people on Hitrea are said to have the power of Abora, which could unlock the Chimera's tomb, but also kill immortals. The three immortals search every town and village for years until their leader Theris stumbles across Max Leoguard, the only human immortals have reason to fear. When Max is told about his power by his uncle, he and his friends decide to go on an adventure to kill Theris and his followers. Max and his friends travel north to find the first follower and finish him, thus saving the one thing Max has left--his friends.
