When Dungeons Arise - Fabric!

Adds large, dangerous structures such as fortresses, palaces, mines, towers, airships and ships, with many enemies and good loot.

When Dungeons Arise adds more than 40 large structures across land, sea and sky, for example:

Fortresses and castles: the Illager Fort, Keep Kayra, Thornborn Towers and Bandit Towers,
Temples and palaces: the Abandoned Temple, the Infested Temple, the Shiraz Palace and the Monastery,
Mines and industry: the Mining System, Mushroom Mines, Scorched Mines and the Foundry,
Towns: the Bandit Village, the Mushroom Village and the Greenwood Pub,
Sky and sea: airships such as the Heavenly Conqueror and the Small Blimp, the Illager Corsair and Galley, and the Undead Pirate Ship,
Others: the Coliseum, the Plague Asylum, the Lighthouse, the Aviary, the Jungle Tree House and the Wishing Well.

The structures generate on their own. They are built as challenges: expect many enemies and several floors. Prepare before you go in.

Bring blocks, food, a bed and a good weapon; clearing a large structure takes time.
When Dungeons Arise - Seven Seas adds more ships.
Dungeons Arise Fixes fixes some advancement icons and loot tables in Nytheria.
Lootr Remastered adds loot from other mods through its built-in structure loot integration.
