"Um... uh, ah! Hello there... your um, wow. Big."

- Lweku to Raferu

Lweku was a Le-Matoran who smuggled things for Vortixx. Like Vescivar, he mutated due to contact with genetics from another species. When he became a Toa of Air, like Mehnera and Liroau he was alone for a certain amount of time.

History
Like all Matoran, Lweku helped in the Contruction of the Mata Nui robot. On Metru Nui during the Dark Hunters many attempts at capturing the city, captured him. On Xia he was forced to labor and later smuggling of goods for arms manufacturing on the island. When he migrated to Spherus Magna, he continued this line of work, considering he didn't know any other. Due to this, he was able to keep his Metru-toran body.

Treasure Hunting 101
Lweku and his so called Vortixx 'friends' become more cocky going after rare artifacts and selling them. Although Lweku never talked he only knew the lines of work as his only kind of work he ever had. Hesitently agreeing to such dark work. One day one of the vortixx were injured, with their blood spraying Lweku along with the other Vortixx, in response of some kind of bad omen, they left Lweku behind. Which is how he came across The Ruins of the Artakha Bull, his curiousity overtook him as he ventured into the ruins, resulting in a cave-in from the numerous traps that ensnared Lweku. He continued to explore the ruins untill he fell into a hole, which happened to be the resting place of two ancient giants old as Tren Krom. He incidently activated Raferu, letting Sydemus know where his next Makuta was. In response the toa Escavo also went to the ruins in order to kind Raferu first before Sydemus.
