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.

To bring down the castle that was home to the Pyralspite trio and Acumen Quilltail, a rival kingdom captured a wild Hooktalon and unleashed her to wreck havoc. It took the combined effort of the kingdom's entire army and Atalanta Pyrope to put an end to the Hooktalon's rampage. When it came time to decide what to do with the wild dragon, the royal falconer stepped forward, volunteering to take responsibility for her. The falconer named the Hooktalon Gorewing, and began utilizing the same techniques he used on his birds. For a time, everyone believed the falconer was wasting his time with Gorewing, as she continued to reject the falconer's every attempt at reaching her. When the falconer brought Gorewing out for a test-run, Gorewing bolted the moment they left the castle grounds. When the falconer tried to stop her, he wound up in a life-threatening situation. To everyone's amazement, Gorewing came back and saved the falconer, proving that the falconer wasn't just wasting his time.
