From Warhammer 40k - Lexicanum
Cryptothralls are long-limbed Necron constructs.
Used as slaves and bodyguards by Crypteks, Cryptothralls are not truly sentient beings and are instead enslaved to their masters will. They are engrammatically compelled to protect their masters with their Living Metal bodies and fierce short-range weaponry which consists of scything limbs and scouring eyes.
