I got one from the fossilized rock thingy from doing the incantation feat. I really, really hope that someone wants this, because in my giddiness to put it up on auction, I didn't realize just how many currants I was putting into the non-refundable listing fee... and now I'm kind of broke. :(
Edit: Is the price I'm listing its actual worth? I'm just going by what the other prices listed for it were.
