This adds 2 different dimensions, the Rethea and the Rethea Islands. The Rethea Islands works just like the end and you have to go to the coords X=0 Z=0 because of how it's generated.
The main dimension, the Rethea, has generation like the nether and it just so happens to have the mob spawning of the overworld.
It adds a biome as well, which is called the Rethea Wastes, which consists of trees around the border of the biome, crying obsidian for the floor, amethyst in the place of dirt, spawns blazes, has structures of the nether, and it has a lot of fossils like the soulsand valley. It adds 2 sets, the Rethea set and the Rethea King set. The Rethea King is a boss that spawns very rarely, maybe impossible, i don't know, and if it does spawn it can destroy you in full netherite armor. It's weapon is a netherite axe, it drops a crystal of which you can use to make a sword that has the capability to give status effects to you. It is a heavy sword, so it will slow you down if you hold it in your hand.
It adds 2 people I know a lot, but I swear the names are completely random. One of them has a nintendo switch, one has a chore list, one has a rethea bow, one has a rethea sword.
it adds garfield, which is harmless until you decide to attack. He drops lasagna,which gives you a lot of buffs.
I might port it to fabric in the future, but I will not do a backport to an older version.
You can put this in any modpack you want, just credit me.
