Things are slow... at first.

The curtains are pulled aside, and now you stand on a short pedestal amidst a crowd of people who are eagerly pushing their way foreword for a better look at your bodies. The people represent a myriad of types and kinds, in fact no one looks much like the other. You realize these are some very unique customers with very unique desires. You, with your relatively mundane appearance, don't attract much attention. Once or twice someone would approach you, and begin to haggle for something small. A slight tingle in the collar would compel you to haggle with the individual, and before long you had acquired a few small changes, and a small pile of low valued coins.

A shy young girl, noble by appearance and dress, had haggled away her freckles, magically splashing the speckled dots from her face to yours. You were a bit surprised, but the money was surprisingly good, and you didn't mind that much.

After haggling with one gentleman over your eye color, you found yourself blinking as a bright flash hit your face. When you opened your eyes, they were golden amber. You smiled, that may even be an improvement.

Another man, a bit older now, haggled away his scruffy set of eyebrows for yours. It seemed a bit silly, you thought to yourself. After all, something like that only takes a bit of grooming to fix.

Things were relatively slow for you, until a stately looking man, distinguished himself from the crowd, as if taking a special interest in you. He puzzled over your face before speaking, "AH! I never forget a face. You're that portal walker, you are. Remember me? I filed your first census for you. Trying to make some extra coin are you? I hope all's going well." The pleasant older man disappeared under a sea of people that began pushing past him.

"Portal walker?" "Like from another world?" "He's from a different world?" "I hear they have unique powers there!"
The voices raised into a roar as all of them started vying for your attention, and your collar compelled you to start the bid.

This, could be bad.
