Dimensions are distinct, separate, and vastly different planes of existence. Aetheria is home to exactly 255 dimensions (most after 99 are blank), from the relatively peaceful Overworld to the terrifying Land of the Dead. Before the ages of the Great Wars, Terrarians inhabited both the Nether and Overworld dimensions. Their ruins are still visible today, manifesting in Nether Strongholds and ruined tunnels deep below the Earth. 

When the time of the Great War struck, the armies of Herobrine tore through the land, ending countless generations of cultural heritage for many Terrarians. They took refuge in a plethora of other dimensions, slowly evolving into mutated parodies of their former human forms, such as the Endermen who were once humans that took refuge in the End.

The animals, brought into the different dimensions by the ancient humans, gradually evolved, becoming the different races that now inhabit Aetheria,

Some benevolent Immortals can be found here, who are able to observe and even communicate with mortals in any other dimension through use of floating crystalline panes.
