Forbidden Island

Forbidden Island (禁断の地) is a northern ice cap island that is believed to be the location of the Mother Lode. According to the in-game map, Forbidden Island is located exactly at Terra's North Pole. For this reason, the island is surrounded by a massive storm with blizzard like weather. Many people have disappeared when trying to explore the island, including Roll Caskett's parents. Barrell Caskett and Verner Von Bluecher are the only Diggers that returned from the island. In Mega Man Legends 2, Mega Man Volnutt travels to the island to rescue the Sulphur-Bottom and its crew, which includes Barrell and Von Bluecher.

Yuna and Gatz are the guardian of the Forbidden Island to prevent Diggers from reaching seal that held Sera and Geetz, escorting the surviving Diggers out or putting them into hibernation but later they stop overseeing the Island after they unintentionally damage Sulphur-Bottom and Mega Man Volnutt was deployed to rescue it.

After the Rush Mammoo has been defeated during the mission to rescue the Sulphur-Bottom, the storm that used to sweep Forbidden Island will stop entirely while Yuna and Gatz are no longer guard the island.
