The Boolong tree is a stubby, evergreen tree that grows thickly throughout Dread Mountain. Their trunks and branches are covered in thick, sharp thorns that make passing through thick growths of them almost impossible. The tree's bark is impenetrable by the thorns and can be used as a shield.
Kin, creatures native to Dread Mountain, possess thick hides the thorns cannot penetrate and simply shove the thorny branches out of the way to feed on the seeds in the cones of the trees. This feeding makes natural paths through the mountain forest that travellers can use to pass without harm.
The Kin and the Boolong trees seem to possess a symbiotic relationship, as the Kin need to feed on the Boolong cones to begin their breeding cycle and presumably, the seeds from the cones are spread and fertilised by their droppings, allowing the trees to spread and grow.
