Anonymous vigilante.

You had spell that you kept for such an emergency but never dared to use before.

It had a requirement that made it rather difficult to train with. Throwing your cloak in the air you quickly cast it before chasing the thief through the crowd.

You are totally naked and no clothing illusions to cover your body, which was the requirement for this spell to work.

The only thing on my body was a small mask that only covered my eyes. It would offer no protection to your modesty or identity if it wasn't for the spell on it. As long as you wore it and only it, no one would recognize you or be able to remember any of your body features to describe it, even magical ways to capture your likeness would only show a blurry shape.

It was paradoxically safe but totally exposed that you rushed through the laughing crowd to catch the thief and take back your mistress gold.

The thief was fast and soon began climbing over low walls in alleys to try to escape you.

She was very good but you had often roamed this streets at night. She was going to be stuck near the stables in the dead end behind the old warehouse.

You cut the chase short by trapping her in this small street, or so you thought.

She threw a grappling hook on a rooftop and started rope climbing to escape you. You used a firebolt to burn the rod just as she had tried to throw the heavy bag of rope or the roof to climb faster.

She recovered from the fall with cat-like agility and took out a small baton, clearly ready to defend herself.

You had no magic left, the bolt took what you had in reserve after using so much in illusion today. You got ready to fight, with your fists if need be but it wouldn't be necessary.

In a truly karmic retribution the bag of gold that the thief had stolen and that you were trying to recover had yield down to gravity and went down to hit her on the head.

Just in time for the end of the spell that protected your identity. You had never used so much magic in your life and if the previous times you had over exerted yourself were a reference you wouldn't be able to do anything of importance until you got a good meal and a night of sleep.

Which left you in an uncomfortable place. You were naked in an alley way in a rather bad neighborhood, without the use of your magic. You had lost Nancy the second you ran after the thief and weren't even sure of the exact address of the gem trader you were going to visit.

You had two obvious options and little else to consider.

You could either steal the clothes of the inconclusive thief or use a small part of the gold to buy something to wear.

The first choice would leave the thief naked in your stead and the second would **** you to face people naked until you found some clothes to buy.
