This isn't as lighthearted as the Thieves Guild. That means no stealing from the Mages Guild and no killing its members. Once in to the Mages Guild, don't screw up. You'll obtain spells, items, and equipment that make being a spellcaster go from nearly impossible to easy as pie. It is a good idea to join the Mages Guild early in the game, especially if you plan on using Magicka. If you're a fighter, try a different guild first and this one will be a piece of cake. These are two of the best ways to make your character invincible, so the reward is high for all of your hard work. There isn't any other way to access this area and it is the only place that you can conduct spelllmaking and item enchanting. However, once you join you'll have access to the Arcane University in the Imperial City. Joining the Mages Guild is one of the most involved tasks in the game.
