From Warhammer 40k - Lexicanum
Apprenteks are the faithful apprentices to Necron Crypteks.
More than mere servants to their masters, Apprenteks are also conduits to their power. They and their staffs serve as nodes and focusing lenses for the Cryptek's abilities, who can even see through their eyes at will.
