Just a Brainstormin: World of Warcraft Regions, Star Wars Planets, Dungeon Dimensions like Levels with a Start and a End (think of MC-End, you need to kill ender dragon to get out). Actually there is no Ghost Biome or somethin..
Name for Dim could be Terra Relictus (Abandoned World in Latin), Boss "The Abandoned", "Ancient Relict".
Ore hhhmmm, maybe Abarid
Redstone+Ender= RedEnder, Render, EnderRed, EnRed...
Maybe that helps
Have Fun!
