Shimmerwing was in the dragon pit walking around, bored not with his usual trainer/bonded rider, as the sunlight casted on his scales they slightly shimmered purple, showcasing that he still had his wild colored scales from youth

He then smelt a new scent in the air was that another human or a new dragon? Either way he walked over to where the scent was, and then found you, as you froze up in fear he nudged you, and you stumbled back, shimmering then did a small dragon chuckle, probably laughing at you
