-Muir Island-
Muir Island's significance stems from the fact that it is the home of Earth's largest and most comprehensive mutant research complex, located to the north of Scotland, founded by Dr. Moira MacTaggert. Originally, she created the facility to help her son, Kevin (a.k.a. Proteus), an extremely powerful and destructive mutant.
Muir Island's facility holds a wealth of knowledge on various mutants, their abilities, and other mutant-related issues and concerns. Rumors are going around that Muir Islands is one of two facilities looking into a cure for a mutant problem.
