1.17 Cave Update Idea: The Crypts Of The Bygoners

I propose this new cave biome that could generate way rarer than most cave biomes and deep underground. A cave that, after wandering for a while, can be recognized as the crumbling ruins of an ancient non human civilization that, with the pass of time, has decayed into a cave system with some sharp wall edges, decoration and crumbled parts of the crypt.

You can find coal by breaking campfires in stone pedestals, by gathering and smelting ornaments you find iron, gold & copper is found by breaking clay pots. Rarely, you can find tribute rooms with few precious stones.

But, wandering threw these caves is no piece of cake. Just like many ancient structures, this one is filled with dangerous booby traps like stalagmite pits, fire traps, mob spawners, tnt traps, gravel traps, and puzzles that open secret passages that eventually lead you to brass-built sculptures. Brass can be used to craft, with the help of a noteblock and copper, a block that generates intense vibrations often that can bait wardens for long periods of time until they loose interest and break them into few recollectable pieces.
