Yan-Su spotted a small shop while visiting the Amarkan province. Stepping into it's dim interior he told the proprietor that he sought unusual things.
The man genuflected then produced a metal box. Speaking the native dialect he said "yunchbox."
The box showed a picture of a white haired man wearing a dark coat. He stood near a boat's bow while men rowed it through icy waters.
Intrigued, Yan-Su asked the public knowledge base about the image.
It responded: "That object does not exist."
Yan-Su blinked, turned, and stepped back out into the bright day.
