*Spoilers*!

This article contains what can be considered major plot, lore, or ending information. It is recommended to play through Core Keeper before reading this article.

The Core is a major structure in Core Keeper. It is one of, if not the most important structure in the entire game, and as such also serves as the game's icon.

The Core is located in the very center of each world and is where all players start the game. In the beginning, it will be in a state of disrepair and must be fixed by the player by defeating the three mandatory bosses - Glurch the Abominous Mass, Ghorm the Devourer, and Malugaz the Corrupted.

Interacting with the Core before it is activated will do nothing and make a failure sound.

Symbols of The Core can be found all across the world of Core Keeper. Not much is known about it currently, and there appears to be a lot of mystery around its purpose and existence, but several locations, items, and tools seem to imply that it may have been revered by the once-thriving civilization located throughout the underground world.

Core activation

When first starting the game, The Core will be powered down. In order to progress, it must be restarted by obtaining three relics, all dropped upon defeat of their respective bosses - the Glurch Eye, the Ghorm's Horn, and the Stolen Crystal Heart. These relics are used to activate the three statues positioned around The Core.

Upon placing each boss relic in their respective statues, the path connecting it to The Core will be illuminated and will charge it a slight amount. New crafting recipes will also be unlocked, which can be crafted at the statues.

Once all three statues have been activated, the paths to The Core, as well as The Core itself, will be lit up, and the player will be able to speak with it. If the player interacts with it for the first time, The Core will mention the ruin of the underground civilization and requests the player for help in restoring it. After this, the character will receive an upgrade, adding the souls tab in the inventory. If not opened already, the player will also now be able to lower the Great Wall.

Until the Great Wall is opened, The Core will only tell the player to open it.

Once the wall is opened, The Core will then give information on the locations of the six titans and their respective biomes. These titans are Azeos the Sky Titan, Omoroth the Sea Titan, Ra-Akar the Sand Titan, Druidra the Wild Titan, Crydra the Ice Titan, and Pyrdra the Fire Titan.

Before defeating Ra-Akar the Sand Titan

• "This instrument, it hath fulfilled its purpose."
• "...come to us ...the barren place far to the <direction>."
• "...find us at the origin of this world..."

• "There, I hath discovered it."
• "If ever thou findst your way hither again, let us be a force for brilliance."

Notes

• The Core's dialogue about titans goes in order of Azeos, Omoroth, and Ra-Akar; defeating Omoroth before Azeos then defeating Azeos, for example, will make The Core's dialogue immediately change to Ra-Akar's.
• The Core's dialogue titan dialogue is not based on the titans defeated in the world, but rather the souls the player themselves have collected so far.

Trivia

• During early access, after collecting all souls available at the time, The Core would mention that "The next soul is still being shaped by the makers of this world."
  • This was most likely a subtle fourth-wall break referring to Pugstorm, the developers of Core Keeper.
