The Wizard is a Bosmer who can be randomly encountered on Solstheim. He can initially be heard muttering to himself, "They said it couldn't be done. They said it. They said it. But they were wrong!", "There's nothing to worry about, nothing to worry about at all...", "The book in my dream showed me...", and "To touch the sky like a dragon..." before casting his experimental flying spell.
If you approach him, he casts his spell and then shoots straight up into the sky, shouting, "It's working, I'm flying! I'm really flying! Hahahaha!" As the spell wears off, he exclaims, "What?! Ooooohhhhhh Nooooooooooo!!!!!" He eventually falls to the ground and dies on impact. The Journal of a Madman can be found on his corpse.
