A cryptarch is one who specializes in crypto-archaeology, which is the study of encrypted matter, such as Glimmer or engrams. In addition to decrypting engrams Guardians find out in the wild, Cryptarchs are also responsible for interpreting intel on enemy species, decoding mysterious technologies, and rediscovering Golden Age secrets.
