The Lone Citadel is a snow-covered stone fortress added by Dungeons and Taverns. It is a rare surface-level ruin that stands on its own in the snowy biomes of the Overworld, with a bridge-linked frame of towers, a library, a crypt and a sealed vault. Its inhabitants are strays and zombie villagers, and it hosts trial spawners that drop the keys to its vault. A player who finds it is rewarded with the "Frozen Remnants" advancement on first entry, and the citadel's vault chests contain some of the strongest loot in this set.

Generation

The Lone Citadel generates in the Overworld, in the snowy biome tag used by the mod's cold structures. It can spawn in about 30 biomes, including Snowy Plains, Snowy Taiga, Snowy Badlands, Cold Desert, Tundra, Frozen Pine Taiga, Ice Marsh, Icy Heights and Spires. It does not appear in warm or temperate biomes.

It shares a structure set with the Stray Fort. Within that set, it has a weight of 1 out of 10, so roughly one in ten placements of the set is a Lone Citadel. Placement uses a random-spread pattern with a spacing of 288 chunks and a separation of 46 chunks. These are the values after the pack's Sparse Structures scaling, so the citadel is much rarer than the mod's default. In a 26 km² sample of generated terrain, no Lone Citadel was observed.

The structure starts at Y=106 and can extend up to 128 blocks from its centre. From outside, it reads as a pale, weathered fortress with a central frame, several towers and a long bridge over the surrounding ground. The frame is built from stone bricks and is weathered by a degradation processor, so many walls are cracked and partly missing.

Layout

A Lone Citadel is assembled from a jigsaw template pool with a fixed central frame. The frame links to a series of pieces:

  • Bridges. Short and long bridge sections, plain straight and curved pieces, T-junctions, and tower-crossing sections. Some bridges are only partly built and end in a failed piece, so a bridge may stop before it reaches the frame.
  • Towers. Straight tower sections and a tower roof with decoration. Larger towers contain "big tower" rooms with several floors.
  • Rooms. Six room types hold decorations and furniture. These include beds, lecterns, bookshelves, skulls, rubble and ice blocks. Some rooms are empty by design.
  • Library. A bookshelf-lined room that holds most of the citadel's book and scroll loot.
  • Crypt. A walled crypt with its own decorations and a crypt wall piece.
  • Pillars. Decorative stone pillars in several block variants (cobblestone, stone bricks, polished andesite, polished tuff).
  • Spawner rooms. Rooms with a trial spawner, described under Inhabitants.
  • Vault. A room with a vault block and its chests, either the standard vault or the boss vault.

The layout is random within these pools, so two Lone Citadels rarely look the same.

Inhabitants

Mob pieces in the frame are chosen at random. The weights are: a failed mob piece (weight 7, the most common result), a zombie villager with an iron axe and leather boots (weight 2), a Stray (weight 3), a stray in armour (weight 1), and a Breeze (weight 1). The structure's placed mobs are strays and zombie villagers.

The citadel's trial spawners are the main threat. Each spawner is a trial spawner whose spawn pool and reward loot come from the citadel's own tables.

  • Stray spawner. The standard spawner in the spawner rooms. Its mobs are strays, and it uses the stray spawner loot table. Ominous variants of this spawner drop additional rewards.
  • Breeze spawner. A spawner that summons breezes. Breezes fire wind charges, and the spawner's projectile pool includes lingering potions of slowness, swiftness and strength, and wind-charged potions.
  • Boss spawner. A boss spawner with a breeze boss. Its reward loot includes the Citadel Boss Key.
  • Failed spawner. A spawner piece that does nothing. These are the most common spawner result.

Loot

The citadel has two kinds of loot: the chests inside the layout, and the reward chests behind its vaults. Its vault rooms are opened with keys dropped by the spawners. A standard Citadel Key (a trial key) opens the standard vault, and the Citadel Boss Key (an ominous trial key) opens the boss vault.

The Lone Citadel Map is an exploration map that points to the citadel, decorated with a mansion marker. It is drawn from its own map loot table.

The generated tables below list the rolls for every chest type. The boss vault table gives the highest-value rolls, including a crossbow in 99% of rolls, Arcane Essence in 48% and Block of Emerald in 42%.

Tips

  • Bring a shield and a bow or crossbow. Strays and breezes both attack from range, and breeze wind charges knock back whatever they hit, which is dangerous on a narrow bridge.
  • Clear the trial spawners before you open a vault. The spawners drop the keys, and a spawner that is still active will keep summoning mobs while you work.
  • Use the Citadel Key on the standard vault first. The boss vault needs the Citadel Boss Key from the boss spawner, which is the hardest fight in the citadel.
  • Expect the bridges to be broken. Some bridges end in failed pieces, so plan a route that does not depend on crossing a bridge to reach the frame.
