Skyther, as the name implies, is a world generation datapack that changes the nether into a series of chaotic sky islands. This datapack also gives the nether the same height as the overworld (y=-64 to y=320), so islands can be more vertically spread out.
Progression is still possible; nether fortresses generate as normal, and netherite spawning has been altered to account for the new terrain: the “small” cluster is unchanged, but up to 6 large clusters can generate anywhere between y=0 and y=-64.
Now all the nether can be a reference to Bastion.
