Thermatrod

Originally thought to be exiles from the Plane of Fire, thermatrods actually developed independently in multiple star systems in the Universe. A thermatrod resembles a molten bipedal creature, though they often walk on their front knuckles to support their heavy frames. Thermatrods sport distinctive raised dorsal plates that resemble hexagonal basalt columns, which researchers use to estimate an individual's age. A thermatrod's hardened exterior varies greatly based on local mineral deposits that make up a thermatrod's diet.

Caldera Mining

Once cooled after the creature's death, the valuable metal in a thermatrod caldera's back plate can be harvested with a successful DC 29 Crafting or Mining Lore check. The most common starmetal found within is adamantine, and a determined prospector can retrieve one adamantine chunk (or two on a critical success) from a single thermatrod caldera's body.
