- Large central monument surrounded by 8 smaller ones, connected by glass bridges.
- No natural Guardian spawns; 2 Elder Guardians are pre-spawned and do not respawn.
- Trial Spawners summon Guardians, Drowned and Elder Guardians, and can drop Trident Trial Keys.
- Defeating Trial Spawners rewards loot and sometimes Water Breathing potions.
- Can be placed into the Resource Pack folder to enable custom key textures.
- Each smaller monument: 1 chamber + 1 Trial Spawner spawning Guardians.
- The lobby (first accessible room) includes a Drowned Swarm Event Trial Spawner.
- Lower area includes a vault chamber, sponge rooms and labyrinth with locked vaults requiring Trident Trial Keys.

- Upper area features a dark prismarine maze, coral displays, oxidized copper and copper bulbs that can be activated with axes.
- Conduit frame room guarded by an Elder Guardian; above it is the boss chamber.
- Boss Chamber: 1 Trial Spawner that summons 3 Elder Guardians. Defeat them to obtain a Trident Trial Boss Key. Rarely drops Heart of the Sea (renewable).

- Ominous Trials increase key drop rates and give stronger enemies:
- Mini Elder Guardians (extra health and damage)
- Drowned with equipment
- Ominous Elder Guardian Trial Spawner: Instead of 3 Elders, spawns 1 Giant Elder Guardian (160 HP, 16 damage).
