Gnolls

Gnolls are vicious, aggressive creatures that occupy a large network of underground tunnels in the Granite Hills, known as the Manara Burrow. Gnolls are hyena-like, with yellow eyes, and are usually large and intimidating. They were able to overpower the Mingruk race and force them into slavery. Their crimes went unnoticed for years until Namino Silverwing discovered the burrows.
