Occlumency turns out to be entirely unlike what I expected. There are no Sherlock Holmes style mind palaces that would give me photographic memory. It just turns out to be magically aided meditation, which will let me order my thoughts and emotions, as well as gain a better awareness of any mental magic cast upon me. The art lets me hide the darker aspects of my personality from Holly, as well as keep her unaware of the negative consequences of our bonding on my end, but it doesn’t offer any more assistance than that.
