Go back to town for some supplies, then wait until nightfall.

By the time you reach town, the sun is close to setting, painting the sky shades of red.

You visit the general store, and the matronly proprietor comes to greet you.

She is a woman of forty, and she is in remarkably good health. Her chestnut hair is short, and her shoulders are broad. she is slightly plump, but that only serves to accentuate the fine curves of her hips and breasts.

"Ah," She proclaims, smiling warmly "Ulric! Good to see you again young man. what can I do for you today?"

"Good evening Angela. I need two bags, as large as you have."

her grin turns sly.

"I have just the thing!"

She disappears through a door behind her counter, and returns shortly after with two massive burlap sacks, ideal for holding grain.

You thank her and pay, but before you leave you have to ask her something.

"I didn't make something of it at the time because I didn't want to look a gift horse in the mouth, but I need to know. Surely you know selling magical artifacts to men is illegal. Why sell me the collar?"

Her smile goes from sly to positively feline.

"What collar would that be dear?"

Her eyes flash with mirth, and she once more heads off into the back room.
