Bonewoods are a species of tree native to the Anagassi Isles, and the only type of tree found on the Isles. Bonewoods are distinguished by their white wood and complete lack of leaves. Their sap is blood red. Bonewoods are generally tall and thin.
The sole source of wood on the Anagassi Isles, bonewood is the primary construction material utilized in housebuilding and shipbuilding, giving them a ghostly white look.
