Professor Shikashi

In Majora's Mask, 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 is a firm believer in the thought 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.

He resembles the old man located in Hyrule Castle Town during Young Link's time in Ocarina of Time. He can also be found in Kakariko Village seven years later. He talks about the history of the Lens of Truth when Link is an adult, and talks about the Sheikah when Link is a child.
