Trivia

 * There is a secret area in a cave in which you don't need to monitor your oxygen. Vindicators, geomancers, creepers, skeletons, and zombies spawn there.
 * This makes this level and the Abyssal Monument the only levels to have areas where the player doesn't have to monitor their oxygen.
 * This was the second level that was confirmed for the Hidden Depths DLC, where it was confirmed in a tweet.
 * This level has a unique ending sequence, in which the ground around the trident begins to disappear and then the platform is shot into the air by a stream of lava.
 * It also has the longest ending countdown.
