About Diabolical Islands
From ModrinthDatapack that creates Nethers with the same floating island generation of Aetherial Islands.
Diabolical Islands
The sister-pack to Aetherial Islands, this world generation datapack changes the Nether to be composed of the same wonderful floating island generation found in Aetherial Islands, but this time in the Nether above a vast sea of lava!
With this datapack, you'll be able to experience soaring islands, flat plains and caves. Structures on rolling hills, and more.
All of the structures and biomes generate with this world type, as they should.
Important Notice
This pack modifies the Dimension's height, which means that you cannot just simply remove the pack from your world after it is created. Create worlds with caution. Additionally this removes the bedrock ceiling and floor. There is nothing under the lava except void.
Shoutout to LNXS!
I have been delaying this project for... quite a while. However, LNXS asked me about a Nether version of Aetherial Islands and offered to commission it for me, and to help take the gallery photos and make the pack icon. Without his help I probably would have delayed this project even longer.. :D Check him out on YouTube!
Want less islands / island clusters?
(WIP: Support coming soon!) Check out the Aetherial Islands: Clusters Edit
Compatibility: Does this work with insert mod name here?
If that mod changes the terrain, one of the mods will probably overwrite the other. If that mod adds biomes, it should be compatible.
