Goblins are one of the known races.
Goblins are made from mixing Gremlins' eggs with Orcs' blood in a ritual performed by Orc Shaman. The goblins inside the eggs are left to grow next to lava, which keeps them warm. The eggs hatch as full-grown goblins.
Goblins are a mix of Orc and Gremlin. As described by Fletcher in The Inquisition, they had the same long and nimble fingers, droopy and triangular ears, elongated nose, and bulbous eyes of a gremlin. Their mouths were filled with sharp, yellow teeth, and sported thick canines in its lower jaw. They stood at a height somewhere between a dwarf and a man and had a skinny build.
