The Eternal Sword allows the wielder power over virtually everything. It allowed Mithos Yggdrasill to split the world into two and create the organization known as Cruxis. It also allowed Lloyd's group to travel to Derris-Kharlan and to merge the two worlds back into one in Tales of Symphonia. You must have a pact with Origin in order to use the sword. You must also have some elven blood. Lloyd gets by that problem with a special ring that Zelos Wilder stole from Cruxis that allows humans to wield the Eternal Sword.
