The empty box.

 Wanda reached into her sling bag and retrieved the small wooden box. it was intricately carved, inside it was lined with plush red velvet. It would have cost a fair amount to make but was not ostentatious. She had held magical artifacts before, indeed there were items intended to dull magical effects radiated by some of the more arcane substances in her masters laboratory. However she had no sense of magical power with these known artifacts and no notion of the magical properties of the box. A skill she would develop no doubt but here and now, nothing.




Meanwhile the search of the small room found nothing either. No items of value, no further clues and no arm.
