From The Heretic Knowledge Vault
Lowest rank of members of the Ensigerum; first mentioned here. Imperatrix Anita (who seems to specialize in sneers, insults and putdowns) thinks it would be a good idea to bust some of the monks back to this rank so that they can re-learn some martial skills. It has been implied that the mortality rate among Initiates en route to the next higher rank of Novice is nothing to sneeze at.
The only Initiate thus far dignified with a name in the comic is Chris.
