The Great Ga'Hoole tree is the most advanced owl civilization in the Kingdom of owls. The owls of Ga'Hoole have figured out how to tame fire and use it for cooking, creating pots and pans along with other things in Bubo's forge as well as the Chaws of the Great Tree. The Great Ga'Hoole Tree has two monarchs, Boron and Barran who are the King and Queen of the tree. There are also Rybs, or the teachers and leaders of the Chaws as well as members of the parliament.
