The Hajial Chase was a primeval hiakk tree forest on New Plympto, roughly four hundred kilometers inland from Phemiss. The Chase was more a section of forest than a forest itself; it was a flat, heavily wooded area separated by the surrounding forest by steep cliffs. Rikknits were abundant in the high trees, and the forest floor was home to unique creatures, such as striders and foragers.

Hajial Chase was utterly annihilated when a Yuuzhan Vong bioweapon razed New Plympto in 27 ABY.
