[ Piglin Expansion (REMAKE) for 1.20.1 is in the works ]
Piglin Expansion introduces new content related to the Piglins. It adds three new cool structures ,that the piglins built to expand their empire in the nether, with some interesting loot.

🐷 STRUCTURES

As I said Piglin Expansion adds 3 new structures, The Piglin Fortress, The Piglin Ship and the Piglin Abandoned Refuge ~~found in the overworld~~

The Piglin Fortress was used to keep important items secure, and also the Piglins built them to mark the zone as "conquered".

The Piglin Ship was used to transport items, but it had an imperfect and weird system to navigate with it, so many of them crashed.

The Piglin Abandoned Refuges are little refuges that some Piglins made in the Overworld to explore it, sadly we all know what happens to Piglin in the Overworld...

🔥 INTERESTING STUFF

Piglin Divinity Gem, this new item can be found on the nether structures.
Piglin Divinity Essence, this item can be crafted by uncrafting a Piglin Divinity Gem.
