Ancient Ruins: Forgotten Age

Ancient Ruins 🏛️

Whispers of a forgotten civilization lie buried beneath the Overworld — if you know where to look.

Ancient Ruins is a data-driven Fabric mod for Minecraft 26.2 that adds 12 handcrafted ruins to the Overworld, each with its own biome, story, loot, and achievement. No new blocks, no code bloat — just pure worldgen, built on the latest 1.21.5+/26.x data pack standards.

🗺️ The 12 Ruins

Every ruin generates naturally at the same rarity as its vanilla counterpart — surface watchtowers that hug the terrain, vaults buried in the deep, and ruins resting on the ocean floor.

– Watchtower of the Plains — a lonely sentinel of the grasslands, meadows and savannas
– Desert Watchtower — deep in the desert sands 
– Snowy Watchtower — snowy plains, ice spikes and frozen slopes 
– Jungle Shrine — beneath the jungle canopy and dark forests 
– Badlands Mine — the red earth of the badlands 
– Mossy Maze — forest floors tangled in vines and moss 
– Abandoned Campsite — a forgotten well in the woods 
– Frost Altar — frozen peaks, an offering to the cold 
– Coastal Outpost — beaches, shores and shallow oceans 
– Swamp Ruins — a witch’s hut in disguise, its chests full of brewing supplies 
– Underground Vault — the deep dark and caverns far below (y = −40) 
– Sunken Ruins — beneath every ocean, a drowned memory 

🏆 Advancements

A dedicated “Ancient Ruins” advancement tab — unlocked automatically when you join a world — tracks your journey: enter each of the 12 ruins to earn its own exploration achievement.

💰 Themed Loot

Each ruin has a hand-crafted loot table using the latest data component syntax — enchanted gear, armor trims, even brewed potions:

– The Underground Vault guards diamonds, echo shards and a mace — occasionally a Protection III diamond chestplate with a copper trim
– The Swamp Ruins (witch-hut variant) rewards brewers with nether wart, blaze powder and ghast tears — sometimes a ready-made swiftness potion
– The Sunken Ruins may yield a heart of the sea
– The Watchtowers hide spyglasses, maps and enchanted books
– No meat in any chest — the ancients were picky eaters
