Kobar
Ruled By: Unrevealed.A very Earth-like extradimensional world, though far more primitive scientifically. It is ruled by a mighty barbaric warlord, Chaynn. His top magician is named Tymon. At 1 time they were tempted to invade the Earth dimension and began stealing military items from the Earth so they could duplicate them. But Doctor Strange showed them a vision of what a single nuclear explosion could do, and they were so appalled that they not only dropped all plans to invade Earth, but wanted nothing else to do with this world.
