The Primordial lands mod is an addon to the Alex's caves mod which adds a surface version of the Primordial caves biome with its entire ecosystem plus some new features such
as the addition of cavemen and their houses or dungeons etc...... the biome is generated naturally on the map among the other vanilla biomes in the game, there are new creatures to
add atmosphere to the biome such as sniffers, frogs, axolots etc.....
With all this there is the presence of all possible variants of the creatures of the biome to add diversity to the biome it is entirely possible to survive in the biome.
