Brush Oinkers are small, forest-dwelling wild pigs, roughly the size of an Earth House Cat. They can be found in the jungles on Elysium's southern coasts. They are very gregarious little mammals. Oinkers typically live in family groups consisting of a male, a few females, and their offspring.

Brush Oinkers are highly curious animals and are willing to try anything once. Upon first contact with researchers, they have shown a lot of interest in them. After they had determined the humanoids to not be a threat, the herd that was initially encountered soon returned to peacefully foraging for bugs, mushrooms, and other tidbits on the forest floor.

Brush Oinkers are the first example of Fae-affected creatures outside the Arcadian Continent. Unlike animals seen in Arcadia, however, they don't seem to show an affinity for Light or Electricity. Instead, the little pigs are more attuned to Earth magic. Individuals affected by Fae Realm energies sport a greenish coloration along with leaf-like structures along their bodies (most notably, the ears). On top of that, their Earth magic manifests in the effect they have on local flora: rapidly increasing plant growth, including trees. Scholars hypothesize that Brush Oinkers may be singlehandedly responsible for the steady decline of grasslands in the southern regions of Elysium. As they push northward, they expand their ideal habitat, while pushing away other animals that are reliant on open grasslands.
