Master Ring

Master Ring is the Final Boss in Riki's storyline in SaGa Frontier. It is an entity that takes control of Mei-ling and uses her to gather all the remaining Rings of Power. It manifested for the first time when Riki gathered all the rings and tried to make a wish to save his homeworld, but the wish backfired, revealing the true evil nature of the Rings of Power. Riki and his party fight it and once they defeat it, they are able to save Mei-ling and reverse the wish.
