The Underdark

Overview
The Underdark is the cave dimension of The Bracken Pack and is great place to locate diamonds, gold and more. A more expansive open cave system is located near the top of the dimension, with more ores in the upper limits of the realm as opposed to the smaller cave systems down below. Small patches of Blackstone and bedrock lines the walls, floors and ceilings of the area.

Accessing the Underdark is accessed by digging to bedrock level in the Overworld.

The Underdark also features a custom mob called the Lost Miner, a passive Illager carrying an iron pickaxe and a diamond. Upon death, there is a rare chance the lost miner will drop a diamond with a note attached.

Be wary of entering The Nether dimension through The Underdark, as to go back to the Underdark you have to go past the bedrock ceiling. Because of this it is recommended to have some obsidian, a lightning book, or some other way of leaving the nether before going down.

Structures
-The giant web structure spawns in the gravel zone and contains cave spiders and shellbreaker spiders with enhanced attack damage, nearly equating to double. Loot necessary for survival as well as things like posion arrows are hidden in barrels surrounding ensnared wagons. Be wary when looting this structure as it contains a ridiculous amount of spider webs, as well as dangerous spiders. -The fossilized giant nautilus structure is located in the eroded biome and is very hard to find, but contains nether gold ore inside its core. Usually you can find it buried under the ground, but you may also encounter it floating in the air, as pictured on the right. -The diamond crystal block spawns in the crystal caves biome, and contains high amounts of valuable diamond ore, including several diamond blocks at the center. Due to its intrisic value, it, along with the biome, are VERY hard to find. However you can imagine the joyous celebration when one does manage to locate this incredibly rare structure.

Biomes
The Crystal Caves is a rare biome that contains an abundance of giant crystal-like structures made of stained glass. A large abundance of diamonds and emeralds can be found here, almost double to triple the amount found elsewhere. An even rarer diamond crystal block structure spawns in this biome. Be wary of the many guardians that also spawn in this biome, despite many of them being out of water.

The Eroded biome is a large-ravine like biome. Loads of blackstone and basalt blocks docorate the ground beneath. It contains waterfalls and many ores, especially emerald. You may encounter lost miners here, which as stated before have a small chance to drop a diamond with a note when killed. Magma cubes, silverfish and Piglin Brutes are also common here.

The Gravel Zone, as expected, contains loads of gravel and dirt. There are also an abunance of large stalactites and stalagmites made of pure dripstone. You can also find the giant web structure in this biome.

The Forest contains waterfalls and fossilized trees that sometimes contain cobwebs. The ground here is also made of tuff.

Lore
The Underdark is a land of bountiful riches and dangers. Dwellers are a stone-like species who live in complex societies and make fortunes crafting and trading with other nations.
