Yaari

Yaari is, amongst other things, a troublemaker. Despite being an Arcane dragon, and therefore supposedly wise and scholarly, his nature as a Mirror will always take over, and he would much rather cause mayhem than read a bunch of dusty old scrolls. Often in partnership with his good friend Apollo, he will play pranks upon the various members of the Flight, especially the hatchlings, who are more easily scared. The older members of the House have tried and failed to keep him under control, but when one has a wayward Mirror under their jurisdiction, there is little one can do to stop them from having their way.
Many other dragons find him rather too boisterous and arrogant for their liking, unlike Apollo, who is charismatic enough to avoid a bad reputation. Yaari's reputation possibly stems from his being what is considered a stereotypical Mirror, and therefore most other dragons are a little wary of him, despite his intentions being simply for his own amusement, rather than to harm any of his peers.
Yaari is often included on night raids or nighttime hunting trips, as his infra-red vision and ability to run fast on the ground makes him an invaluable asset when airborne or larger land prey is scarce.
In spite of his lack of popularity amongst the other dragons, Yaari knows how to take their snide comments with a pinch of salt, and simply returns to plotting his next escapade.
