When I was born, a clever mage, who was also my mother, made for me a triptych: three panels, attached in a row by hinges, depicting paintings of our home. The middle panel depicted our capital city, where we lived. The left panel depicted my mother, her hands raised as if in the casting of a spell. The right panel depicted the Arx, the great tower of knowledge where mages learned their trade. The flanking panels were each half the width of the middle one, so they could be folded inward, and the image could be hidden. And strangely, my mother had built a lock into the triptych. Once folded, the triptych could be secured. I did not know why it would need to be locked. There were no secret or blasphemous things depicted in the paintings, as far as I knew.
