A temporary fusion dimension born due to unknown high-dimensional disturbances (later revealed to be related to the cracks in the "Origin Wall" and the scattering of "Cosmic Cube" fragments). The X-Men (including Mutant Nation), the Justice League, the Avengers and their related villains were involved in tracking the abnormal energy (actually the "Gauntlet" resonance) in their respective universes. There are conflict areas with basic physical rules in the world (such as magic, mutant genes, and super-technology interfering with each other), but a fragile balance is temporarily maintained.
