|Species||Matoran, Toa, Turaga|
Olwi was once an Av-Matoran on Linna Nui. When the Dragon Makuta attacked the island, Olwi, Hiiah, Antin, Miko, Rwalis, and Saenti fought against them. During the battle, they were suddenly teleported to a great hall where the angel Jwi transformed them into Toa. Olwi's element changed to Ice-Light in the process.
As a Toa, Olwi went with the others over the Endless Ocean to Magi Nui, where they found the legendary Seventh Council of the Magi. There they recieved the Staff of Unlimited Powers and went back to Linna Nui, where they fought the Dragon Makuta and blinded them with the Staff. Botar then came and took them to The Pit, but Dentarius escaped.
Later, when Matoran from Metru Nui start to move into Linna Nui, the Toa Filin sensed that some evil was rising again, and knew that this quest was not for them. They then gave their powers to Macku, Gami, Kani, Zilu, Kopeke and Wimou. Olwi gave his to Kopeke, who became the Toa Libris of Ice.
As a Turaga, Olwi and the others led the islanders of Linna Nui. They are now living happily there.
Olwi was cold and quiet, and spoke only when needed. Most of the time he kept his distance from the others; not because he disliked them, but because he was thinking of future matters beyond his teammates' imagination. He often had visions from Mata Nui, although he never revealed them; he recorded them in the Blog of Olwi.
Olwi wore the Kanohi Huna, the Mask of Concealment. He could control the powers of Light and Ice easily when his element changed, and he held two Icepikess as a Toa.
