To say you bought this valuable-looking mirror for a steal was an understatement. As the seller - who seemed quite eager to hand it off - had described it, this antique had been passed down generation through generation, going back centuries. And it was in pristine shape; its jewel-encrusted trim practically untouched, and its surface giving off a reflective gleam. Its origins, however, were a mystery...

That deep, resonant and monotone voice echoed around the room, like it was drilling into your psyche. As the flames parted, a new sight cut through the darkness - that of a strange, mask-like face, hued in an ethereal mix of warm colors with a stern yet dutiful eyeless gaze.

A wry look crossed its features, as if appraising you.

"You are my new master? Hmm. A pleasure. I am more used to residing within castles or... other establishments. Your abode, while more... modern than most, shall do nicely."

...You blinked - what exactly did you buy?

"Astonished, are we?" it remarked with a droll chuckle. "I figured as much. Perhaps it would be best if we started from the top, as they say..."
