Although Ziggy tends to come to school in his street clothes, he does own, and is often required to wear, a set of robes. This is just a picture of him wearing them. The color corresponds to what level wizard the wearer is. In this case, grey is a level 6 (which is equivilent to a high school graduate as far as wizards training goes). The trim and cape colors also mean things, but I won't go into them here (ask nicely and I might write up a guide on it :3). Anyway, I hope you enjoy this, rather simple, pic
