Mirror Dragons are known for their savagery and their hunger. They are social predators that run in immense packs. The species originates from The Abiding Boneyard, but their migratory nature sees packs roaming to every corner of the world.

Physical Attributes
Mirror dragons are a medium-sized dragon that possesses two sets of eyes. The larger set allows them to see light, while the smaller forward-set pair allows them to track their prey by heat signature. Each mirror dragon has a rigid, fanned crest that is used in displays of dominance. 
Mirrors are one of the few dragon species that prefer to do the bulk of their travel across the surface of the earth rather than over it. They are tireless on the land, running their prey down at sprint speeds of up to 50 miles an hour. These predators are capable of short-duration flights, but will quickly tire and return to earth. This may be due to their metabolism, which is a formidable beast; the average adult mirror will consume its body weight in prey each month.

Social
Mirror dragons prefer travel and hunt with their own kind, and do not mix well with other dragon species. They form transitory packs, made largely from whoever happens to be in the area at any given time. These leaderless packs merge, grow, and split constantly. A typical pack size ranges between 5-40 members. Lone mirrors by choice are an anomaly. A more typical encounter with a single mirror dragon occurs when an individual is injured or incapable of keeping up with the pack. Injured mirrors have been taken in and treated by other dragon species, but as soon as the mirror is physically capable they leave to rejoin the hunt.
Mirrors do not put much stock in chatter; that's not to say that they're incapable; most simply don't see the need. A dragon knows who its friends and allies are, and if one wants to communicate they should do so by action, not pithy words. 

Lairs
Mirror lairs are temporary occupied structures owned by no pack or clan. They are constructed from whatever material can be easily scavenged. These structures are abandoned when a pack had depleted all a hunting ground and moves onto a new territory. After the prey population in a depleted region has had a chance to recover, a new mirror pack may move into the vacated lair.
