For everyone that likes Warhammer 40k Tabletop and Dawn of War Games or anything to do with Warhammer 40K.
Crypteks are Necron technological specialists whose purpose is to study the highly advanced and ancient technology of their race.
Their main fields of study include dimensional dissonance, singularity manipulation, atomic transmutation, elemental transmogrification and countless other reason-defying technologies. They are masters of the scientific and technological and in many ways a Cryptek's powers mirror those employed by the psykers of other races such as the Imperium and Eldar. However they differ in that instead of using a mutant mind to channel Warp energies, the Cryptek employs arcane science to harness the universe's fundamental forces.
What a Cryptek often accomplishes with his technology is nothing short of magical to the eyes of the lesser intelligent races. With his knowledge of arcane sciences, a Cryptek can transmute a foe into liquid Adamantium, turn them into a speck of dwarf star matter, set the air ablaze, call down eldritch bolts of lightning and other equally impressive feats of technological arcana.
"Any sufficiently advanced technology is indistinguishable from magic." - Arthur C. Clarke
Likewise, any sufficiently analysed magic is indistinguishable from science.
The amount of sense this makes is precisely none!
which makes perfect sense!
