"What's beyond the ocean?" you ask, still hoping against hope that this is merely some obscure part of planet earth. Perhaps there's a logical explanation after all... temporary insanity? Amnesia?
"I don't know," he shrugs. "I leave the ocean to the pirates and crazy men. Solid land is the place for me!"

A twinkle in his eye hints that he's had some run-ins with not-so-learned wizards in the past.
More eager than ever to find a wizard, you persist in your questioning.
