Centaurs

The Centaurs live on Centaur Island, the northwestern accessible island in the south ocean area. Most of their territory is inaccessible to visitors, but they do maintain a zoo which is open to anyone with an Orga eye. There are some rather dangerous creatures in the zoo, which the Centaurs must have at least some skilled fighters to have captured them in the first place.

Centaurs hate the Orga, and they are related to the Winged Centaur civilization which was destroyed by Orga. However, I have never seen or heard of the Centaurs actually taking action against the Orga. Apparently they are content to hold their island and take no action against the Orga elsewhere in the Lok'Grotons.
