Lesovikk

Lesovikk is a Toa of Air who was a member of the first Toa team. He joined the team about 100,000 years ago but has not completed his destiny yet. He is currently visiting The Pit but is not a prisoner there.

This is a description given by Greg Farshey:

LESOVIKK: Toa of Air and a member of the first Toa team ever in existence. Originally stationed on one of the southernmost islands, the team clashed with a wandering tribe of Zyglak. During the battle, Lesovikk hesitated for a fatal split second. As a result, the Zylglak gained the upper hand and killed all of the other members of the team. Only Lesovikk escaped. Returning to his home village to warn them of the impending danger, he found that the local Turaga had gone mad and shipped the entire Matoran population to the realm of Karzahni. These included Lesovikk’s best friends, Sarda and Idris.

Guilt-ridden, Lesovikk became a wanderer, convinced he was not worthy to be a Toa. An attempt to rescue his friends from Karzahni met with failure (nor did he realize that those particular Matoran had already been transported to Voya Nui by that time).
