Named after the short story of the same title (ehm, the short story belongs to me, of course ^_^...Wyvern's...Wyvern's...did that make you want to go read it? :P ).
The rider enjoying the flight is named Pari'lin (Pah-ree-lin) and he ought to be! It's the first time in his life that he's been able to stretch his wings, so to speak, and take a Serp'dol (the creature's who's head you can't see) above the canopy of his home in the grove and enjoy the freedom of the sky.
The background of the sky was done in photoshop- no it's not premade, I did it myself for once and I'm pretty pleased with the outcome, though I think it could be better.
