Wizard Blues

I WISH THEY HAD TOLD ME THAT BEFORE I ENROLLED!
Twin brothers Ocean and Sky inherit magical talent and dream of becoming wizards. They thought they had it made when they enrolled at a prestigious university of magic on a remote island. On graduation day a path to great magical power is laid before them. There's just one catch — they must give up their youth forever. They take the leap and become powerful wizards in the bodies of old men, but something goes wrong. Their disguise short-circuits leaving them young again — two very unconvincing wise old wizards. On the mainland they encounter a mystery: some invisible evil is killing the dwarves in a mountain mine. Can the brothers convince the dwarves that they are powerful wizards and uncover the secret of The Beast before they become its next meal?
