Destruction of Hell's Core

Located somewhere in the floating island Cube, Hell's Core is used as a laboratory where Demons are born, as was the case of Minerva Orland, and also reborn, as was the case with Tempester and Jackal.[2] According to Lamy, this is because of a contract made with the Underworld King, making Tartaros an immortal Guild.[1] The entire mechanism seems to be controlled by a Demon with tentacle-like extensions as these creatures were taken over by Mirajane Strauss, who then proceeded to use these in order to destroy Hell's Core.[3]
