It's about an emperor/magician who wakes up after having fallen asleep while fighting a destroyer of worlds type thing After he wakes up he visits the capital of the empire he built and learns what has happened in the time he was gone He's a void mage and after learning that the void mages got hunted down by the church he tries to find his old comrade who is also a void mage Also he fights in a tournament and wins it. This is all I remember, I read it like a few moths ago and have been trying to find it. Thanks
