Adelstan, the Stone World ruled by the dwarf god Baldnoggin, represented by the Earth symbol.
If our adventurers manage to open the Water Portal on Caeruleum, they will learn that they have to open the Portals to the remaining Worlds. Each trip to another World requires a harrowing journey through the Elderwyld.
Once they arrive on Adelstan, they will find themselves in vast subterranean caverns and tunnels. The Upworld of Adelsten is daily tormented by bolide impacts and is a perilous place to survive.
The dwarves of Adelsten have built their homes below ground, deep enough to protect them from cave-ins triggered by impacts on the surface above.
This is not to say that all dwarves are united or that they are bound under one rule. Several dwarf kingdoms exist on Adesten.
Each has their own unique customs. All but the Upworld dwarves, called Scavengers or Scabbers by Underworld dwarves, are connected by subterranean locomotive.
The subterranean world of Adelsten is also inhabited by its fair share of orcs, trolls, gnomes, humans, goblins, elves and other species. Many of these non-dwarven races call Shield Warren their home.
Others make their living alongside the Scabbers, their dwellings and pathways hanging from the undershell of massive marsupials known as anvil backs to protect their roving villages from the angry skies.
