Rokanan was the third-to-last emperor of the Old Exekian Empire. He ruled during a period known as the Age of Shadows, when the Empire was economically prospering but appeared socially diseased. After the events of Matta's Mutiny, an infamous rebellion which led to the death of Rokanan's would-be successor Prince Caspar and nearly cost Rokanan his life, he was forced to abdicate.
He is mentioned by Apollo as having ordered the capture of a group of escaped human slaves. When the mission went wrong and the humans were slaughtered, Rokanan nonetheless praised Apollo for his efforts and promoted him to a higher rank. His coldness toward humans appalled Apollo even then.
