This is the Ancient Dragon avatar of Verkin Raven and Stickman Ingmann, a giant and wonderously detailed serpent persona you can buy for L$2400 (about USD$9.50 at current rates) in the glorious island of Aggro. When you wear the dragon avatar, you can sit and fly, and perform many other dragon-esque activities via a heads-up display-- even curling your claws. (Here's Raven and Ingmann's exhaustive product release notes.) I'm nominating it in New World Notes' search for SL's most precious item, as determined by its beauty, price, and other variables.
What's your nomination for SL's most precious item? Go to the Open Forum, read the criteria, and post your suggestions. In December, Iris Ophelia and I will select ten finalists for a reader vote.
