Goblins

Goblins are small green beings that reside all over Ethrel. They live similarly to humans, but are far less intelligent.

Goblins may appear dumb, but their language is the most complex in all of Ethrel. Their vocalizations are so rapid and erratic, that other beings had no idea it wasn't gibberish for ages. Similarly, Goblin writing looks like simple toddler-like scribbles. It was assumed it was just that until it was seen that a Goblin note passed to another separate group knew exactly what it said and responded accordingly.

After this revelation, people rethought their ideas on Goblin intelligence. It was concluded that other beings do not interpret the world in ways Goblins can. Their thriving populations in places considered uninhabitable by other intelligent creatures suggests that they can survive in ways others can not comprehend.
