The Ancients Awakened mod features two new biomes called Chaos Biomes, which are counterparts to the Evil Biomes. A world generated with the Ancients Awakened mod will always feature both the Inferno and the Mire. The Chaos Biomes spawn upon world generation. These biomes are dangerous and should generally be avoided by new players until they get better gear.
Unlike the Evil Biomes, the Chaos Biomes will not spread. However, after defeating the Wall of Flesh, the two Chaos Biomes will increase in size. Similarly to the Evil Biomes, the Chaos Biomes can overlap with the Desert and the Snow Biome.
The Mire[edit | edit source]
The Mire is one of the two Chaos Biomes added, with a swampy, poison, and amphibious theme. It features a large lake in the center of the biome, leading to an underground cave with Mire Pods. Breaking a Mire Pod will summon The Hydra, as well as give a useful item to the player. The Mire only spawns enemies during the Night, and in the day inflicts Mire Fog to make it nearly impossible for the player to see.
The Inferno[edit | edit source]
The Inferno is one of the two Chaos Biomes added, with a volcanic, fiery, and draconian theme. It features a large volcano in the center of the biome, leading to an underground cave with Dragon Eggs. Breaking a Dragon Egg will summon The Broodmother, as well as give a useful item to the player. The Inferno only spawns enemies during the Day, and in the night inflicts Ash Rain which damages the player over time.
