Knowledge Elemental

Some knowledge is so powerful it can't be contained within a single mind. Even if contained in specially created books, a bit of the knowledge always leaks out. It is said that even minor books leak their knowledge a little. If enough books in an area leak such knowledge, it interacts with other sublime knowledge in an area. Eventually the concentration of knowledge leads to the existence of what in lack of better terms is called a knowledge elemental. It is raw knowledge and power set free. It has only a mockery of sentience, truly no more than an irritating and misleading mirroring of knowledge fragments. The knowledge has only one purpose: to be known. Yet it's heavily fractured and raw, not fathomable to an ordinary mind at all. In their attempts to insert itself to others, the knowledge elemental becomes an aggressive threat, as it attempts are harmful and even lethal. The sudden outbursts of knowledge are disrupting and destructive, often taking the shape of spell-like effects. Magicians usually have to exorcise such manifested knowledge from their libraries. Given the relative commonness at certain areas, many libraries accept then as a given and rather use spells to ward them away from their bodies, instead of dispersing them. Though such wards are relatively complicated they are usually permanent and less of an effort than to fight knowledge manifestations again and again. As it occurs an area can only sustain a given number of knowledge elementals at all, so if one manifested another is highly unlikely. A place that could create more then a few knowledge elementals at a time, would have to contain absurdly high levels of knowledge and can be discarded to the realm of pure fantasy and wishful thinking of knowledge seekers and cultists.
