A massive and ancient library that contains all of the knowledge ever collected about spellcraft, rituals and other arcane teachings. Because a lot of the content is forbidden by modern law, it is heavily guarded and protected by numerous enchantments and runes that only the most determined assailant could defeat.
Founded by four powerful mages during the third age, it once was home to a school of magic. However, after a disastrous event involving several senior students, the school portion was shut down and moved to a far away location. That part of the library has now been taken over by storage archives.
