Comments: The Dark Dimension is a synthesis of realities merged by mystic means into a single domain. This process of merging realities came to a stop when the realm of the Mindless Ones was joined to the Dark Dimension (though Dormammu later attempted on one occasion to use the power of the Evil Eye to bring Earth into his domain). By its nature, the Dark Dimension is a very fluid reality, consisting of pockets of stability within a more chaotic whole.
