From Ardrana

Goblins have flat faces, broad noses, pointed ears, wide mouths and small, sharp fangs. Their foreheads slope back, and their eyes are usually dull and glazed. They always walk upright, but their arms hang down almost to their knees. Their skin colors range from yellow through any shade of orange to a deep red. Usually a single tribe has members all of about the same color skin. Their eyes vary from bright red to a gleaming lemon yellow. They wear clothing of dark leather, tending toward dull soiled-looking colors.

Goblin speech is harsh, and pitched higher than that of humans. In addition to their own language, some goblins can speak in the kobold, orc, and hobgoblin tongues.

These small, evil humanoids would be merely pests, if not for their great numbers. On Ardrana, they are nearly ubiquitous, being found in every region, and especially fond of raiding Human and Elven settlements.

Note: Goblins originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
