Scaldseat

Scaldseat is an underwater volcano off the coast of Issylra within which are chambers that were once the domain of Moradin, the All-Hammer.

Description
From the surface of the Ozmit Sea, Scaldseat is marked only by a column of smoke rising from the water. The tunnels within it are filled with toxic fumes.

History
Inside the chambers beneath Scaldseat is the Core Anvil which Moradin used to craft his finest creations, including the first dwarves and the Prime Trammels used to banish Tharizdun in the Calamity.

When Vox Machina sought help from the gods to combat Vecna, Ioun taught them the secret of how to craft more Prime Trammels and showed them the location of the Core Anvil. They teleported to Shorecomb, a coastal town five miles from Scaldseat, sailed out, and dove to reach the hot tunnels beneath. There they fought with magma bulettes, encountered ancient constructs, and crafted the Prime Trammels that they soon used to banish Vecna.
