====Spirits of Intellect/Knowledge====
You know how humans leave behind shades and nature can sometimes manifest incorporeal spirits? Well, a Spirit of Intellect is what happens when a spirit and human (and some other things too) fall in love with each other. If their relationship is one of True Love, it can create a sentient mass of energy and knowledge called a Spirit of Intellect. SoIs are vulnerable to sunlight, but they can inhabit magical vessels to protect them from the sun, in exchange, they must do the bidding of whoever owns the vessel. They either take on the initial personality characteristics of whoever owns the vessel (only the characteristics at the time of introduction though) or they take on the characteristics of their owner's first impression of them (so if they change owners, they can stay almost the same if they met the owner before). This mutability may disappear when they get powerful enough. Essentially being a self-aware database with a personality, they're most useful as living repositories of knowledge and as advisers. They can get scary powerful over time, since for them knowledge literally equals power.

*'''Bob''': Harry's Spirit of Intellect who inhabits a human skull. He helps Harry work on spells and enchantments and also gathers information from around Chicago and the Nevernever, serving as a something between an adviser, a spy, and a supernatural weather station, being equipped by training and inclination to map out the changing "flows" of magic. Harry first got him when he was a teenager, so Bob's kind of a horny bastard, much to Harry's ongoing frustration. Having worked alongside wizards for at least a millennium, Bob is scary powerful and intelligent, and knows secrets that have him on Mab's hit-list. It's easy to underestimate the power of someone who could be killed by taking him outside and smashing him with a hammer, but in spiritual terms he's a heavyweight, going toe to toe with powerful spirits, tearing down complex and powerful wards without much effort, and surviving a hit from wards made by someone whose other wards one-shot a twelve foot tall magic-resistant goat faery. That's just his magical muscle, so to speak, to say nothing of his centuries of experience and instinctual knowledge of magic.
**'''Evil Bob''': Because spirits of intellect are made of knowledge, if they lose a large amount of information, that info can take on a life of its own, like cutting a starfish in half to get yourself two new starfish. "Evil Bob" is a manifestation of all the knowledge Bob gained from working with a certain S-Ranked necromancer we may or may not have mentioned above. Evil Bob is a twisted, enormously powerful version of his progenitor, loyal only to Kemmler's memory. He's also evil, to the point where he manifests as a skeleton in a freaking SS uniform. It's a testament to just how powerful Kemmler was that the comparatively small time Bob spent with him produced a spirit that's more than an equal for the one spawned from the collected experience of working with countless other wizards for centuries. Its also a testament to how greatly Kemmler twisted Bob's very being that the persona was loyal only to Kemmler instead of whoever owned the skull, and that it retained its own identity rather than the one of its current owner. Bob hated this part of himself, and locked away as many of the memories as he could. Impartial spirit of intellect, eh? 

*'''INSANE SPOLIERS (Bonnie)''': Harry's daughter by Lash, Bonnie was all set to pop out of Harry's skull like Athena and Zeus during the events of "Skin Game". Harry was unaware of her existence up until this point as Mab told him he had a psychic parasite that was causing his increasingly painful migraines, which technically wasn't a lie. Fucking faeries. She's adorable and likes pancakes. She's also a horrifyingly powerful spirit, being the Scion of a Starborn mortal wizard who's one of the most dangerous practitioners alive, and the echo of Lasciel, a freaking Fallen Angel who was known for her intelligence and plotting. It's implied that she has all of their memories, and spiritual might proportional to that knowledge. Considering Bob's new living arrangements, it's entirely possible that she will be Harry's lab assistant going forward in the series. 

*'''Athena''': The Greek goddess Athena popped out of her father's skull fully grown, the result of one of Zeus' many, many, many, many, many, many affairs. She had so much power that she immediately ascended from Spirit of Knowledge to god status.
