Hooktalon Dragons are a two-headed breed named for the long, curved claw that grows on the first finger of each of their hands. Their skin is tough and covered in razor sharp, tooth-like scales, and as they age they grow a dense, keratinous club on the end of their tail. Wild Hooktalons live in migratory, matriarchal clans around deserts and hot scrublands, hunting and stealing kills from other dragons as they please. They are notoriously ill-tempered and the females, being the largest and most aggressive of their kind, will often lash out at their male counterparts in brief, explosive disputes over anything and everything. The only creature with which a Hooktalon will not fight is itself: though the dragon has two heads and thus two brains, a strong connection between its brains allows them to function as one.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Z Peso resides in the lair of the Hellfire Wyvern clan Akhathen, though he is not considered one of their males and is given only the reluctant tolerance of his fellows. They've tried to have him transferred into the mines below one of the underground outposts under their control, but the bloodscale dragon Ranrar and his daughter argue in his favor, pointing out that his aggression is genetic, and could be useful in the production of warriors for the clan.

Z Peso's left head speaks only in rhymes, much to the right's annoyance. Around the left head's neck is a tag that reads "Avispa del Montanas", or mountain wasp. One of his future daughters is owed to neighboring clan Venata under this name. He seems optimistic about his fate.
