When one of the body parts are destroyed, said body part grows harming thorns and spawns a True Eye of Cthulhu, which does each of the first four attacks. The player must destroy each of the hands and the head to open the core, the Moon Lord's weakspot. Reaching a tentacle at the player (if attached, it spawns Moon Leech Clots, who can regenerate health back to the Moon Lord if not killed).Firing a Phantasmal Deathray, a massive laser.Spawning Phantasmal Eyes, who home in on the player.Summoning Phantasmal Spheres, which explode after a couple of seconds.The Moon Lord has various deadly attacks, such as: After this event, the player has one minute to get ready for a fight, because after this period, the Moon Lord will appear, and the fight with it will begin. (Each of these flavor text comes in after the first, second, and third destroyed pillar respectfully.)Īfter destroying the last pillar, the screen will vibrate and the music will fade out. You are then tasked to destroy each of these pillars, but as you do, something appears to not be right, as flavor text afterward says your minds goes numb, your body gripped with pain, and hearing "otherworldly voices" lingering. If you attack the cultists and kill the Lunatic Cultist who appears after, you unlock the Celestial Events, where four pillars (Nebula, Solar, Stardust, and Vortex) are summoned into your world, summoning celestial monsters near their location. In the actual game, the player will encounter the cult in the Dungeon that used to house the old man possessed by Skeletron, in a small group appearing to be worshiping the Moon Lord. An Old Man is also possessed by Skeletron during this time and becomes a steward to the Dungeon. She mostly completes her work, implied to have created Skeletron Prime, The Destroyer, and The Twins, only needing to complete the mechanical brain. In order to accomplish this, they kidnap a Mechanic, place her in a Dungeon, and force her to build replacement parts for the deity. After many years, a doomsday Lunatic Cult led by a fanatical zealot began seeking to methodically revive Cthulhu and bring about the end of the world. They also ripped out one of its eyes, part of its skeleton, and chunks of its brain implied to become the Eye of Cthulhu, Skeletron, and the Brain of Cthulhu, respectively. Though they were unable to kill Cthulhu and mostly died out, they crippled the deity and banished it to the far side of the Moon, where it became the Moon Lord seen in the game and plotted its revenge.

Prior to the events of Terraria, the world was attacked by Cthulhu and nearly destroyed, but it was stopped by an ancient race of Dryads connected to the planet.
