Goblins are strange creatures. We are certain that they are a Gaia-native species yet have seen a remarkable number of similarities between goblins and the Ghorkai.
Both are green-skinned humanoids with sharp pointed ears, largely proportioned facial features, too many pointy teeth, and an innate understanding of even the most complex technology. Yet no evidence of Ghorkai has been found on Gaia, gods be good. Old legends are just that, for we have not met many denizens of myth...unless one counts a dragon, a subgaian colony of dwarves, and goblins, that is....
We were certain these beings were myth too but here do we see them or, in the case of goblins, we only see them when they want us to. Yet they mean us no harm for the goblins of Chomolungma have worked diligently for the dwarves for generations and are even respected among folk who are as protective of their compliments as they are about their secret forging recipes.
Goblins are shorter, on average, than humans, reaching the maximum height of an average human 12 year old on maturity. They are slight of frame and gangly of build but, despite that, are remarkably strong.
Highly intelligent and dextrous, goblins are responsible for much of the modernisation of dwarf technology, especially the complex and 'fiddly' bits of it. Though rowdy (especially under the influence of uisge, their favourite beverage which they made from cave mosses and lichens) and ill-disciplined, they are loyal and, if you give them a difficult problem to fix, will become almost obsessively focussed on it.
Like dwarves, goblins originated from Eirè and Brytton/Skotia, and are thought to have shadowed the dwarves' migration, escaping their own form of persecution.
