Sanctum

Overview
Sanctum is a quiet dimension, remnants of an advanced ancient civilization lie below the white landscapes covering the broken buildings of a once great people. Ruined treasure lies dormant within some of the ruins left by the civilization. Netherite is hidden in many of the old structures of Sanctum, but buried deep within the machines and buildings.

Sanctum is also an anti-grief dimension, with TNT disappearing, lava evaporating into obsidian, and fire dissipating from the ground.

Sanctum is one of 4 dimensions that contains its own unique boss.

To access Sanctum you must dig all the way down to the bottom of the nether near bedrock level.

Structures
-The obsidian hand is a hand made of mainly obsidian and polished blackstone bricks. There are 3 netherite blocks in the structure: 2 blocks in the palm of the hand, and one block inside the arm.This structure replaces the "village" vanilla structure.

-The buried gear is a gear made of mainly polished andesite, polished blackstone bricks, cracked polished blackstone bricks, polished blackstone brick stairs, obsidian, smooth stone and bedrock. The structure also contains 30 iron blocks (270 iron ingots) and 4 ancient debris in the middle of the gear. This structure replaces the "bastion remnant" vanilla structure.

-The stone army is a structure with 2 variations. One of them is hardcoded: this means that it will always be the same. This variant has a tomb, with inside: 64 rotten flesh, 41 bones, a protection IV book, a compass, 2 netherite ingots, a wither rose and a wither skull. The second variant of this structure is a jigsaw variant: this means that the army will be randomized. This variant won't have a tomb, but it will sometimes have netherite scraps inside blast furnaces. Both variant has lots of damaged anvils that can be taken for use. This structure replaces the "bastion remnant" vanilla structure.

-The ruined sanctum building is a structure made of mainly obsidian, cracked polished blackstone bricks, polished blackstone brick wall, smooth stone, chains, clay, chipped and damaged anvils and bedrock. The structure also contains 4 evoker fangs spawners. These should be the player's top priority as they can easily kill an unprepared player. There are lots of dispensers on all the floors with loot inside:

Floor 1 has cracked polished blackstone bricks, stone, smooth stone, obsidian, compass, lodestone, damaged anvil, and smithing table.

Floor 2 has cracked polished blackstone bricks, stone, damaged anvil, obsidian, compass, lodestone, smithing table and netherite ingot.

Floor 3 has cracked polished blackstone bricks, stone, damaged anvil, obsidian, compass, smithing table, netherite ingot and netherite boots.

Floor 4 has cracked polished blackstone bricks, stone, damaged anvil, obsidian, compass, smithing table, netherite ingot and netherite helmet.

The dispenser on floor 4 with the most anvil on top of it will always have: 16 stone, 6 cracked polished blackstone bricks, 4 obsidian, and 1 bedrock, allowing the player to get bedrock in survival. You can also find the Fang magic book here as well

-The Sanctum dungeon is a massive complex found within The Dark Soot Dunes biome with three main portions: the underground tunnels, the pyramid, and the balancing vault. The entire structure is encased with a single layer of bedrock and is impenetrable aside from the openings of tunnels branching out from underneath the pyramid. The network of tunnels often contains rooms with loot, "sleeping" netherite statues that attack the player if disturbed and will emit redstone jolts, expanding area of effect clouds that wither, blind, and starve players, and the occasional angry enderman. At the center portion of the pyramid contains an immobile boss known as "Project Ruination" which, once defeated will grant access to the Cosmic Cornucopia Vault portion of the structure. The vault contains valuable loot, such as experience bottles, a single netherite block, and a room containing 27 wither skulls. Eventually it will also contain much more custom loot and more variation to make exploring the structure more rewarding and fun.

Biomes
The City biome contains blackstone structures, rumored to be the remains of a giant ancient city once goverened by gears and macinery of all kinds. The stone army, gear, and ruined sanctum building structures can all be seen here.

The Land biome is a wasteland that contains sand and blackstone brick spires. Nothing but sand can be seen for miles. Sometimes, if you are lucky, you can find a rare obsidian hand structure.

The Dark Soot Dunes is a work in progress biome all about patches of black and grey sand. It contains large blackstone spires in a similar vein to that of the Crystal Caves biome.

Sanctum Oceans can appear in both biomes as well as invisible vindicator mobs known as marauders. The marauders have enchanted(Sharpness 3, Knockback 3, Looting 1, Fire Aspect 2) netherite swords, increased player follow range, movement speed, but low player detection range. If a band of marauders are killed they will not respawn again in the same area.

NOTE: Sanctum oceans have a bug where structures spawn on the water. A possible fix may come in the future, or 1.18, but for now, this is a unfixable bug.

Lore
Sanctum is one of the oldest dimensions and was created to be a crowning gem among the other realms. However, due to the overambition of its inhabitants, and the destruction of their mod, the realm eventually became an unending wasteland. The Builder, the mod who was killed by his own people, created this dimension and governed a race of people there. Over the centuries however, they quickly advanced in power and knowledge until they reached the point in which they realized they could overpower the mod ruling them.

This ended up backfiring when the Builder died, because the land began rejecting its inhabitants. All of the plants perished, their sun cooled, reddened, and gave up on traveling its path across the sky. The atmosphere thinned and ash snowed endlessly from above. Those formerly living there were then forced to adopt a nomadic lifestyle, scattered throughout all of the other dimensions as wanderers. These people were then renamed as "Outlanders."

Despite it all, Sanctum still gets some attention from the occasional archeologist and treasure hunter looking for valuable artifacts to plunder beneath the dunes. However many avoid its surface, afraid of its cursed legacy and its relative position near The End.
