A Keeper is someone (Telepath I think) who stores secret information inside their mind. Their mind should be close to impenetrable which is why they are the Keeper and call one at that. Prentice was a Keeper, he was a Keeper of the black swan for info such as what Alden extracted from his mind before it broke. This is how he found Sophie.
