EDIT: Typo and misinformation fixed for The Nil.
If I feel like putting them in. These are very likely the only dimensions that will be available. They will now be referred to as Realms, though Dimensions works as well. Theyre interchangeable. I really need imput for this one
Globe: The main world. It consists of a realm not unlike the Earth: it has an incredibly diverse ecosystem. The most diverse of any other realm. Name comes from another word for the earth, which is what Globe more-or-less is.
Inferno: Looks like hell. it's a volcanic world where the sky is red. Under the surface are caves and chasms that ravage the underground. These chasms hold more life that the surface. Inferno is another word for hell, and also refers to the realms fiery appearance.
Aether: Looks sorta like heaven. Sky is describable as gold or orange. Consists of large land masses floating high above the surface of the flat-ish world. The majority of life forms live on the floating land masses. Aether is the air the gods breathed in Greek mythology.
Eldritch: A dimension full of the most uncouth and bizarre evolution tactics and somewhat off physics, which further lead to ever stranger evolution lines. The land is mostly made up of mountains or plateaus with overhangs being a fairly common sight. Before the rift that flung creatures from Globe to other dimensions, this place was apparently barren of complex life forms. Looks a lot like a weird dream or painting. Eldritch means "of a strange country, pertaining to the Otherworld" or "in a foreign land, exiled", which fits its realm pretty well.
The Nil: [Yes, properly, its 'The Nil' not Nil.] The only organism that can naturally move between realms make their home here. Land masses the size of islands float around scattered in seemingly empty space. If one focuses, they can hear static. Gardens filled with flowers from every other dimension can occasionally be found here, along with its only (albeit essential) native plant: grass (greenish-blue). Its also the only dimension where human relatives CANT be found, and where there are no naturally civilized creatures. This is the hardest dimension to get to, and perhaps the most inhospitable for life (Other than the creatures native here, which don't even rely on their dimension's given resources.) Ironically, the creature that can travel dimensions is the key to transdimensional travel without relying on the only little rifts that still occur in very specific times. Nil means "nothing", which is what mostly fills up this world.
Again, tell me what you think. This is not officially implemented yet, because I want to know if you would want this or not. Im pull myself between 'yes' and 'no' right now, so I really need a second opinion.
