Thera

Thera is the name of the planet that the Aether encircles above, specifically far above its atmosphere. The Aether is described as a belt around the planet's atmosphere, similar to that of a planetary ring. While Thera is not the main setting of the mod, it still serves a very important purpose both for lore and in-game, as it is also the planet where the Necromancer's Tower is located.

Thera also has a handful of blocks to it's name, such as Thera Grass and Therawood Log.
