The Endless Dimension

The endless dimension would be a dimension where the sky is always night, yet much more light is shining from the sky than in a normal overworld night sky. Stripped down to everything but the ground itself, the dimension would be aesthetically pleasing with its cosmic feel, which would make it a great place to build. While it is night, mobs that normally would spawn in the dark will not here (just like the nether), and any mobs that do spawn would be able to spawn at any time. There is no day or night cycle in this dimension, so clocks would operate much like they do in the nether or end. Lodestones could also be used in this dimension, as well as beacons. Cosmic variant biomes would generate here as well as cosmic variant mobs, and to top it off, structures such as abandoned towers or abandoned castles could also generate.
