Ether Legacy is a mod that aims to bring the content of the already obsolete mod, Aether I, to the current version of the game, i.e. something like a “port” of this old mod to the current version.
The way to access the Aether Dimension is the same as before, by creating a portal out of 4×5 Luminous Stone Blocks and emptying a bucket of water into the portal. That is, the same as creating a portal to the Nether, but changing the obsidian for the lightstone and the lighter for a bucket of water.
Once we access the dimension of Aether, we can find its characteristic terrain, where large floating islands are inhabited by strange creatures. We will also encounter its mythical dungeons and mythical bosses.
