From DreyNet

Slik is DedLee Sylent's twin brother. Poised and astonishingly handsome, Slik is the more refined of the Sylent Twins. He is currently Shad’s right hand man.

He has the ability to dominate the will of others, hypnotizing them instantly. He has no affect on dreamcrafters.

The Sylent twins are tied somehow to Dylan.

Slik Sylent was formerly named Smooth Sylent.
