The Castle is the main structure in Niffelheim. It houses the player's workshops, storage, and other buildings.

Basics

The Castle is located in the center of the player's region. The Citadel can be interacted with to upgrade the castle structures and repair them if necessary, or entered to access the workshops, chests, or mines below. Additionally, a healing throne and a trophy room can be found inside.

The two spots to the left and to the right of the Citadel allow the player to construct two farm buildings: Vegetable Garden, Chicken Coop, or Sheepfold.

The player can teleport to their Castle from the world map anytime.

Upgrades

The Castle consists of the citadel, walls, and towers. Each structure has its own durability bar which depletes when a skeleton horde or other players attack that structure. Upgrading the Castle is essential to withstanding enemy attacks.

The player starts the game with a basic Citadel with no Walls or Towers built. They can construct and upgrade these structures by interacting with the Citadel. The appearance of the structures changes with each upgrade.
