LAYERS

In Abyssal Descent the world is split into layers, with the power of Immersive Portals "dimension stacking" you can mine right through bedrock to seemlessly enter the next layer with no loading screen.

Delvers' Beginnings, is the first layer containing a diverse underground ecosystem rich with valuable resources rarely found in surface caves; Crystal Caverns, Pink salt spikes Lush ancient deltas, unique mobs and bosses from 15+ mods can all be found here!

The Undergarden is a dark, subterranean world located far deep below the Deepslate of the Overworld. The flora here has adapted to their conditions and can grow anywhere, independent of light. Strange creatures call these dark lands home, and are plagued by the invasive Rotspawn, monsters originating from a chaotic, mysterious realm.

The Infernal Crossing is an exceptionally dangerous series of magmatic caves and canyons shrouded in darkness. Giant Centipedes, Ghouls and other horrors reside here waiting to turn any intruders who enter their domain. Conquer (or succumb) to the Infernal Crossing and reap the supernatural rewards this layer offers.
