The Crystallization Cauldron is the apocalyptic weapon created by the insane King Valentine before his death. It is capable of artificially creating red Phozon Crystals normally only found in the Netherworld, though it does so by absorbing Phozons from Erion and thus is likely to be dangerous to the environment. While it will respond to King Valentine's voice openly, it will primarily obey the commands of those possessing the Ring Titrel, which results in a scramble by several characters to possess the ring throughout the story.
