Ukulam

Ukulam is the fourth, and least-explored of Castrovel's continents and is located north of the Colonies. Unlike the three other continents, Ukulam has never been significantly colonized as it is the undisputed domain of dangerous plants, deadly beasts, and gigantic fungi. Any attempts to domesticate Ukulam by one of Castrovel's other three major cultures (the lashunta, the elves, and the formians) have failed due to the continent's unrelenting flora and fauna.

Khizars

Ukulam is home to the fourth major sentient speicies of Castrovel: the plant-like khizar people. These live in small, mobile communities of a few dozen individuals that frequently relocate (staying in the same location no more than a few years) in order not to overly tax their surrounding environment. Visitors to Ukulam are welcome, but are advised to treat nature with similar respect when in the company of khizars.
