Incendium is a datapack that completely revamps the nether, way more than what Minecraft did in the 1.16 Nether Update.

Incendium adds 8 unique biomes to the nether. Do you bravely venture through the perilous Quartz Flats, wander the mysterious Withered Forest, or battle your way through the steep Infernal Dunes? Each biome has a unique personality and story to tell. With unique block themes in each biomes, opportunities for new farms for technical players, 3D biomes, and stunning terrain, there is truly something for everyone.
To complement the lovely biomes, there are 9+ structures for you to explore and conquer. In the Ash Barrens, the Forbidden Castle stands forebodingly, with courageous Piglins defending its treasured loot - one of the largest and complex random structures in Minecraft! Alternatively, you can conquer the ominous Sanctum with its illagers defending dark secrets and strong weapons. The skeleton chef Torte defends his Quartz Kitchen, and the Withered Director his Nether Reactor. What will you conquer first?
Every mob you defeat and structure you conquer has its reward - Incendium pays you handsomely with rich loot and custom weapons! Defeating the Hovering Inferno could earn you the Trailblazer - a flame-spewing bow. A high damage, but taxing Greatsword of Sacrifice hides within the Forbidden Castle's walls, along with the helpful Hefty Pickaxe. Or maybe you prefer to find the Hazmat Suit to protect you from all types of poisonous attacks. There are over 25 items to forge your own playstyle with!
No datapack would be complete without its own mobs to fight you. The Toxic Heap is home of the agile Toxic Slimes, and the Withered Forest is haunted by the Restless Spirits. On the other hand, you could go on a rescue mission to save the Ghastling from the Abandoned Tower - in return, it will defend you from Ghasts. If none of this is challenging, you can summon the all-powerful Hovering Inferno boss for a difficult and dirty battle.

As the inevitable rewrite draws ever closer, it’s time we answer the question of what is going happen to the current Incendium port. And the answer is that it is being rebranded as Incendium Legacy Edition, the main reason being the Rewrite will be a separate mod page when released because we know people would accidentally update from the port to rewrite if we used the old mod page. The second reason being is I want to keep Incendium Legacy updated for at least a few updates after the rewrite releases so people aren’t cut off immediately because they can’t/won’t update to the rewrite. This does mean eventually this version of incendium will one day cease to be kept updated but I will try my best for as long as it stays convenient. But don’t despair because not only is this a 26.2 port, but this is also 5.5.0. That’s right an actual update this time around. I promised myself that whenever we get close to the rewrites release I would go through the port and give it a one last hoorah update to clean it up as best as I can. Buts that’s not all: this update includes a few simplified additions/changes from the rewrite, some balance changes, and whatever performance improvements I could fit in.

This is an unsupported version of Incendium! Use at your own risk.
The datapack itself is fine, it's not experimental in any way. Instead, support will not be offered for small issues, incompatibilities, or other bugs.
If there is a game-breaking bug or crash, we will provide fixes for it.
Stardust Labs is currently using all of its time it has for Incendium, and putting it into the rewrite.
When the rewrite is released, upgrading from this port to the rewrite may not be possible, or will involve resetting the nether dimension.

MASSIVE thanks to Rei for making this update happen! Without Rei, Incendium would have completely skipped 1.20.5. So many things broke in 1.20.5, and it was simply not worth my time. Thank you!
