Professor Shikashi
From Zelda Wiki.org
Professor Shikashi[1] is a wise old man who spends his time in the Astral Observatory, looking at the stars. He has opened his observatory and the path leading to it from Clock Town to the Bombers, so that they may use it as their hideout[1]. He always has wisdom to impart, and is a firm believer in the thought that one should develop one's interests while they're young[1]. He resembles the old man located in Hyrule Castle Town during Young Link's time. He can also be found in Kakariko Village seven years later. When Link is a child, the old man is fascinated by the Sheikah. He talks about the history of the Lens Of Truth when Link is an adult in Ocarina of Time.
