Lenk

Lenk is one of the members of Team Retard and is a Diabolo.
Lenk came from a village called Kornstead, where he lived with his parents. But it became clear very fast that Lenk wasn't an ordinary person. He had a devilish look and people from the village feared him because he looked different. Not only did he look different, Lenk also possessed special abilities. He was able to manipulate shadows around him. His parents didn't know what to do with him.
When the Nathaïr's Followers came to Kornstead and asked for Lenk, everyone was surprised and scared. They took Lenk in as they saw him as a new prophet. They experimented on him, trying to activate his shadow abilities in order to find the location of the Books of Visku. When Lenk turned 18, the Nathaïr's Followers decided to sacrifice him for their lord Sartor. But when they tried to sacrifice him Lenk burst out his magical abilities, destroying the hide-out in the process. 
Now, Lenk is on the run for the Nathaïr's Followers.
