Ilia

Ilia (イリア Iria) is a young woman of about 16 years, who lives in Ordon Village. She is Mayor Bo's daughter. She keeps a close eye on Colin and appears to view it as her duty to keep him out of trouble. She is also extremely close with nature and heals Epona when she is hurt at the beginning of the game. Ilia is the daughter of the mayor, but would rather spend time in the wild. Ilia appears to be one of Link's closest friends. Towards the beginning of the game, she is hit with an arrow and kidnapped along with Colin by a group of enemies, which leads into Link trying to rescue her. Link eventually locates her in Hyrule Castle Town, but when she sees him, it is apparent that she does not recognize him. Telma reveals that Ilia has lost her memory and cannot even remember her own name. She has been taking care of Prince Ralis who she had found. Telma had taken them in and was helping Ilia care for the Prince. Telma says that Ilia has a lot of courage and that Link should share his courage with her.

Before she arrives in Hyrule Castle Town, she is held captive with Impaz by some Bulblins in the Hidden Village. Impaz helps her to escape and in return she gives her the Horse Whistle, a whistle in the shape of Horse Grass that can be used to summon Epona. Ilia was apparently locked in her room at the beginning of the game making this item for Link but never got the chance to give it to him.

Renado looks after her in Kakariko Village, before Link restores her memory and she stays there for a while afterwards. After her memory is restored, she gives Link the Horse Call (which is the item that jogs her memory), saying that she made it for him and was going to give it to him before he left.

During Lanayru's narrative of the Fused Shadows, Ilia, along with Link, depict Hyruleans as they watch the creation of Hyrule and the Triforce. Afterwards, she appears blank-eyed (representing the people blinded by the Triforce's power) and attempts to kill Link with a knife. She is presumably killed by Link in the narrative.

During the game's ending, Ilia and the rest of the Ordon children are seen returning to their home inside a carriage. She is last seen witnessing Link's departure from the village.

In concept art, Ilia was drawn with the pointed ears of Hylians. It's possible she was originally intended to be a Hylian, but any Hylian heritage in Ilia is unknown.

Certain hints in the game have stated that Ilia may have a romantic relationship with Link, although it it never confirmed. Some examples may be at the beggining of the game, it seems like before King Bublin attacks, they are sharing a moment. The same happens when Ilia gets her memory back, when Link and Ilia are looking into each others eyes. When all the people leave the room, Talo is at the window, and his eyes suddenly widen. This may hint that Ilia and Link kissed when the screen was facing Talo. This also can be possible based on Talo's reaction.

Trivia

 * Ilia is a trophy in Super Smash Bros. Brawl. The description reads: Link's childhood friend and daughter of Bo, Ordon Village's mayor. She's always considerate of Link and looks after his horse, Epona. One day, however, she is kidnapped by enemies and loses her memory. Her kidnapping is what prompts Link to set off on his adventure.
 * Ilia seems to be based on the character Saria from Ocarina of Time because both are very close to nature, and are childhood friends with Link. In Japanese, the letters "r" and "l" are the same so that would make Ilia "Iria" and Saria, or "Salia" and Ilia.
 * She could also be based on Malon, who is the caretaker of Link's horse in Ocarina of Time. They also both lived near or on a farm, as well as they both teach Link how to play Epona's Song, although Ilia can't play the song and merely instructed Link what to do to play the song, which was blowing into Horseshoe Grass.
 * Being based on Malon would make her based off of Marin in Link's Awakening, which, in turn, makes her based on Princess Zelda.
 * It is possible to beat the game without restoring Ilia's memories.
