Professor Shikashi 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. He always has wisdom to impart, and, having been interested in astronomy since he was a child, is a firm believer in the idea that one should develop one's interests while they're young. Professor Shikashi is also the one who informs Link about the importance of the Moon's Tear. Like so many others in Termina, Professor Shikashi also had a disruptive encounter with the Skull Kid before Link's arrival.
He resembles the old man located in Hyrule Castle Town during Young Link's time in Ocarina of Time. This old man can also be found in Kakariko Village seven years later. He talks about House of Skulltula and about the history of the Lens of Truth when Link is an adult, and talks about the Sheikah when Link is a child.
