Sorcerous Supplies

Sorcerous Supplies is the store in front of the dam. There, you can buy magic related items, such as the crystal ball and magic mirror. To build it, you need to reach Level 8, have a certain amount of Sims and a certain amount of Simoleons to build. After building the tower it'll unlock The Book of Spells quest.
