I have to agree with all of the above. I got mine by sheer luck. I was hanging out on the street corner in Central Plaza back in the Halloween era. VMK_Annie came into the room. She and I had talked some before, and "had dinner together one night, lol" She said, "What Coriander, no Inferno?" I said, "Sadly, not" She said, "Well, here you go!"
At that point in time I dc! I was frantic to get back and when I did, it was in my inventory! Bless you Annie, wherever you are! Sadly, she is no longer with us; but I will be forever grateful!
