Levias

Levias is a character in SS undefined. He is a wise, whale-like Sky Spirit who has served as the protector of the skies for ages and lives in the Thunderhead. Levias has a particular fondness Pumpkin Soup, which Pumm always offered on a sky isle that had a perpetual rainbow above it, before the Thunderhead engulfed it.

Biography
Before the goddess Hylia transferred her soul into the body of a mortal, she appointed Levias as the guardian of the skies. She also left the Sky Spirit a hint as to the location of the Triforce, which was one of the four parts of the "Song of the Hero," a melody that would unlock the final trial for the chosen hero. However, at one point, Levias was corrupted by evil forces and became plagued with Bilocyte, possessing him and causing Levias to attack anyone who comes near.

After learning of Levias from the Headmaster Gaepora, Link speaks to Owlan and learns that although Levias can be found in the Thunderhead, he has become possessed by Bilocyte and will not listen to reason. He tells the hero to talk to Pumm, who makes annual Pumpkin Soup offerings to Levias. Link then places a basin of Pumpkin Soup in an island of the Thunderhead to lure the beast out of the cloud sea and, with the aid of his Loftwing and the newly-learned technique Spiral Charge, removes the parasites. Upon the removal of the last visible parasite, a Bilocyte occupying Levias' blowhole emerges. Link removes this parasite as well, and upon hearing that Link was searching for the Triforce, Levias informs him of the four parts of the "Song of the Hero" are needed to find the it. Levias then instructs Link to track down the three surface dragons, Faron, Lanayru, and Eldin, to learn their parts of the melody. Once he has done this, Levias imparts the final part of the "Song of the Hero" to Link.

Etymology
If spelled as Levia, it means "combine forces" and "join", which is what Levias does in both Skyward Sword and Hyrule Warriors with Link. Levias' name is derived from, a mythological monster from Biblical text. Fittingly, the modern Hebrew form of the word means "whale."
