Crypteks are like a cross between an engineer, archiver and head butler. They see to the running maintance of the tombs systems and most fancy stuff like resurrection orbs and serve the Royarch (Necron King/overlord thing) hand and foot. They seem to be some sort of lesser lord caste but are looked down upon by many of the more 'aristocratic' and senior necron lords.
