Atheron has Arc in a vulnerable position during training. It appears to be cold out, the dragon has just the spot to keep him temporary. Though Atheron is a nice dragon, he can't help but indulge in little fantasy moments, eating the last lund? :3
Don't worry, Arc will be released eventually, much to his playful annoyance. Atheron will be sure to offer nuzzles, licks, and if Arcturus is unlucky, another trip inside him.
