The Unseen University is the primary institute of wizardry on the discworld.
The Unseen University's most valuable facility is the library, containing 12 spellbooks and the vast majority of spells available to wizards. Also inside the university is the student lounge (or advancement room) where wizards can be trained in their primaries by the guild. The gym, which contains the beginners' tome and a donation chest, is also a good place for student wizards to get useful items and spells, as well as honing their skills on Dwmmigh.
Joining the guild is a fairly simple task, achieved by typing 'join' in the hallway outside the student lounge. Upon doing this the player is greeted by Ragnel, who will explain the basics of magic and provide the student with a copy of Master Woddeley's Occult Primer (which is also a talker), and recruit them into the guild to become an 'Unseen University Initiate'. The student can then advance using the guild's student lounge and choose an order when necessary.
The Lecturer in Recent Runes is a high level wizard who automatically teaches commands when you have sufficient skill to learn them. He can be found wandering the university grounds.
The Communications Imp is an enslaved demon who will automatically grant new guild titles to wizards when they reach certain guild levels. He can be found wandering the university grounds.
Dwmmigh is another enslaved demon with a slightly more sinister purpose, that is to provide wizards with a target for offensive spell practise (similar to a training dummy for melee. He can be found chained to the floor in the gym.
Each order of wizardry is led by a senior wizard.
