Ilia

Ilia (イリア Iria) is an attractive 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, and during the course of the game the pair are drawn closer through adversity. This is often interpreted by fans as an indication of possible romantic involvement, along with similar hints during Link's discourses with Princess Zelda and Midna.Another reasonable possibility of involvement, is when Ilia has her vivid flash back when Link and Ilia where looking at each other in a deep romantic way. In this cut scene, there may also be a point of why all of the people wanted to give them "privacy" together, and for some reason that Talo was entertained and wanted to watch what would happen.There is an extememly small chance that while the cutscene was only showing Talo smiling at them,that they could have been being afectionate with eachother, or maybe even kissing. 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 afterwords. 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.

Ilia is a trophy in Super Smash Bros. Brawl.

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.

Trivia
so that would make Ilia "Iria" and Saria, or "Salia" and Ilia.
 * Ilia seems to be based on the character Saria from Ocarina of Time because both are very close to nature, and are chilhood friends with Link. In Japananese, the letters "r" and "l" are the same
