Forge?
Pyrellium is fully compatible with sinytra connector, use that for playing pyrellium on forge.
Is this compatible with X mod?
Pyrellium was built with compatibility in mind. It works alongside all major Nether mods and fits naturally into both vanilla and modded environments.
Will you be adding more biomes or features?
Pyrellium is currently in beta, this means more features are on the way. Adding more biomes itself will be unlikely, but stay tuned for new mobs, items, and other features.
Hey this looks a lot like Lankasters Nether.
Yes. Pyrellium started as Lankasters Nether, but eventually grew to big to be just a datapack, and it was decided to switch over to making a mod. Lankasters Nether is still available as it's own project for archiving purposes, but it is recommended where possible to use Pyrellium instead.
