The Four Heavenly Kings were four monster kings that used to rule on Pangaea a long time ago. For an unknown reason (perhaps the rise of the the Three Beast Kings?) they retreated to the heavens, but when Errick accidentally summons them with the Star Rock, they crash land back on Pangaea and take several characters as hostages, forcing you to fight them as the final level bosses.
After defeating them, Centauros breaks the Star Rock into twelve pieces, which gives twelve different monsters the powers of the Zodiac. This allows you to begin unlocking ??? monsters at the Shrine.
