Gaepora is the keeper of Skyloft's legends and lore, meaning he is one of the chosen few who knows the secrets of the Goddess Sword and The Surface. Interestingly, his outfit greatly resembles that of Rauru's. He is also the one who sends Link to The Surface to rescue Zelda.
Because Gaepora is the keeper of Skyloft's legends and lore, Link has to talk to him at the Knight Academy on a number of occasions, depending on Link's current objective. This includes information concerning the Ballad of the Goddess, a clue that will point Link to the Isle of Songs, and the Triforce.
If Link enters the Academy via the chimney using the Clawshots (which also allows access to Zelda's locked room) at night, Gaepora is revealed to be the one who taking bath (via a grate in the bathrooms ceiling). Gaepora's bathing prevents Karane from using it.
In the epilogue, Gaepora is briefly reunited with Zelda at the Sealed Temple.
In an interview with Nintendo Power, Eiji Aonuma has stated that Gaepora was always planned to be knowledgeable and wise (he was originally going to be a priest that was heir to the legend of the goddess), so the designer based his model after this. His coincidental resemblance to Kaepora Gaebora made them choose the name Gaepora. This also continues the trend of residents of Skyloft being named after birds.
- ^ "Eiji Aonuma Nintendo Power Interview: Talks Skyward Sword, Zelda Wii U" (English) [Question: The headmaster’s name, Gaepora, is pretty similar to the owl’s name from Ocarina of Time, Kaepora Gaebora. The headmaster even has owl-like eyebrows and a hooting laugh. Were these characters intentionally made similar, or is that just a coincidence? Aonuma - The headmaster holds a wide variety of knowledge (he was originally designed to be the priest who was the heir to the legend of the goddess), and so the designer made him look like that in order to present a wise and dignified image. He wasn’t actually designed around Kaepora Gaebora, but since he did end up resembling him, we gave him the name Gaepora.]
