The Ahko tree is an important tree in the Meó empire, it takes the form of one of the five deities as Áhko. Despite its name, it is not a true tree as it does not produce wood but rather a thick more grass like material. Historically it has been used in the Empire as a building material or as a fuel source. It contains a large amount of flammable oils, which combust when the temperature is hot enough, causing the tree to almost explode. This is one of its adaptive mechanisms for reproductions (cf. Eucalypts). Because of this property, it is strongly associated with fire within the empire and the religion of Siela.
