Master Yadeen was a Carthaki mage who specialized in stone magic. He taught at the School for Mages of the Imperial University of Carthak. He was one of Arram Draper's instructors when the boy was in the Lower and Upper Academy.
Yadeen was born in one of the tribes of the heartland of Carthak. His colleague, Sebo Orimiri, also came from around there, although it is unknown if they share the same exact tribe. It is also possible that Sebo and Yadeen lived near the tribe of Kylaia al Jmaa. Sebo cited that Yadeen's origins are the reason why he believes in animal divinity and magic, and also that he believed in Enzi's existence.
Yadeen is a large burly man.
Yadeen has only appeared in Tempests and Slaughter so far.
