Beyond the supposed black hole (which acts more like an interdimensional wormhole of some sort), there's an "alternative" universe where planet Sagar is located. Despite its atmospheric similarity with Earth, the world is also very different from ours, inhabited by many extraterrestrial species. The Sagar Tree, a mystical place, is ruled by the peaceful pink-skinned Trobbits. It seems that the Trobbits can tap their magic into the forcefield which lies behind the Sagar Tree. Likely, many sorcerers and magical creatures on Sagar can draw energy from a mysterious source set in a parallel plane.
