Tom's Structures
Tom's Structures generates new structures in the world, each with its own loot, for players exploring overworld, Nether and End terrain.
What it does
The mod places structures in the overworld, the Nether and the End, and the loot in each one is its own. Players find them while exploring, and the contents aim to reward a visit with items that are not in vanilla chests. The author describes the structures as cozy, interesting and fun to loot, and the contents can change between versions.
Tom's Structures runs on Fabric, Forge, NeoForge and Quilt, across game versions 1.21 – 1.21.11 with 12 release versions. Both the server and every player need it, because the generated structures and their loot have to exist on each side. The mod is released under the MIT License and is not open source.
Key features
New overworld structures
New structures generate in the overworld, adding places to find while travelling through unexplored terrain.
Nether and End structures
The mod also adds structures to the Nether and the End, extending the places to explore in those dimensions.
Unique chest loot
Each structure has its own loot, so the items found inside differ from one structure to the next.
Loot tables change by version
The probabilities of items in chests vary between versions, and the loot tables can change when the mod is updated.

Use cases
Exploring new terrain
Players who travel far from spawn can find the added structures and loot while they explore the world.
Adding loot to a server world
Server owners can add the structures to a world, giving players extra places to explore and loot together.
Who it’s for: Players who want more to discover while exploring, and server owners who want new structures in their worlds. Because the generated content and its loot change between updates, it suits players who accept that the contents can change.
