While you descend into The Living Infinite, you will encounter different Biomes which appear as different water layers. New Biomes are added from time to time in content updates.
All Biomes in a layer are equally likely to appear, with the exception of the first layer, where the Atlantic Waters have a higher spawn chance (50%) than the others (25% each).
During the Biome transition, you and your crew will gather for a Dinner sequence.
