In the sidequest "Magician's audience" you help the magician Cid to gather attention to his magic street show.

Cid is standing outside the Bavelock Gym, and no one is watching. If you are willing to help he will give you 5 posters that you put up on the walls in Bavelock telling about Cid's show in the city. When you have put up all 5 posters at their designated locations, you see there are two people watching his show, Gruss and Aiden.

If you talk to Cid again you receive a reward of 2 Magic auras for the help.
