Warmind
From Destinypedia, the Destiny wiki
A Warmind is thought to be an artificial intelligence designed for war or combat strategies.This was during the Golden Age, before the Collapse. This idea is supported by the fact that the name of these "constructs" is a combination of the words War and Mind. Only one Warmind has been named, Charlemagne. This is kept in Charlemagne's Vault, and is guarded by the Cabal. All in all, very little is known about Warminds.
