Moving Swiftly, Bleeding Light,
Can't be seen, Nothing in sight,
Moving Forward, Left Behind
Shadows clash, fighting blind.
Chiral visions, lead the way
Visible echos, save the day.
See yourself, not as you are,
Looking glass, avatar.

In a recent plot on Kaerwyn, characters volunteered by their players were transformed frequently, ruining their clothes.  It turned out a hostile entity had taken over a tailor's shop and was using it to bolster his profits.  In order to stop him and free the tailor, the affected characters had to locate 8 altars spread through town and challenge them each.  At the 6th altar they challenged, Nathan was at present a Minotaur and several other characters were also present(though I didn't include them for cost). 

Once they activated the altar in an arena of mirrors, they were given the above riddle, then attacked by an invisible flying snake entity, which could only be seen in the mirrors...or by people trapped in them.  Nathan's turning and looking for it, and listening for instructions on where to strike!
