In SAGA 6 and 7, two new dungeons were introduced, Maimai Ruins and the Water Layer. Maimai Ruins can be reached via Tonka Island and paying a man 200 gold to take you to the island on which the ruins are located. The Water Layer is located in the Titanian World and, for a period of time until SAGA 9, will be the only area in that world that is opened to players. Waterlayer can only be accessed via the Sky Tower linking the Emil World to the Titanian World (above) and the Dominion World (below), and players have to undergo a series of quests to retrieve a Sky Tower Key to gain entry to the Tower and defeat the Titania Dragon boss monster. These SAGAs also mark the appearances of Catty Sora and the twin Cattys Kurumi and Wakana, the implementation of the lvl 90 weapons and the Breeder Joint Job.
