Okay, we called him a wizard in the screens we posted (well, doesn't he look like one), but our cloaked friend will have to settle with just being a wise guy. In Ocarina of Time he could be found wandering Hyrule Market
mumbling things about the Sheikah. Later, after Hyrule Castle was commandeered by Ganondorf, the wise man told Link about the Lens of Truth in Kakariko Village's well. This time he has much more important news to dispense. The end of the world. In a conversation with Link he warns, "Three days from now, the moon will bring an unimaginable disaster."
