Like most children growing up, Bret had that one special friend who influenced them greatly, for better or worse. Unlike most children, however, that key influence was a majestic lunar dragon! A creature fascinated by the lowly creatures of Golarion and their ways of life, Azzatazirx had resided in Numeria for years, curious as to how the primitive species of the planet reacted to the incredibly advanced technology that had fallen into their lap... and watched their antics with some amusement.
But Bret was an anomaly: she hadn't planned on revealing herself to any humans. Rather, he stumbled into planet-bound lair by sheer accident during a game of hide-and-seek, finding her residing among the remains of whatever technologies she had collected and still functioned, studying them to sate her curiosity. At first, Azzatazirx intended to eat him to keep her location secret, but the young human, his enraptured curiosity overpowering his fear, spat forth a constant stream of questions, giving the lunar dragon pause. His thirst for answers amused her, and she indulged his queries with a patient collection of answers. By the time he left, Bret had elevated himself from nuisance to bemusing student in the dragon's eyes.
Over the years, Bret would constantly return to Azzatazirx, often dragging back technological trinkets he found interesting and asking an endless stream of questions about his discoveries, thoughts, and revelations. His wit grew sharp and he started to mimic aspects of the lunar dragon, such as hording curiosities and thirsting for much more complex answers. In time, the impossible happened: Azzatzirx began to see Bret as something of an offspring, the hatchling she'd never had, and she took pride in his development.
But one early morning, Bret snuck out to meet his teacher, only to find she been seriously injured. By what, Bret couldn't say, and Azzatazirx would not speak of, but his best educated guess was some sort of strange alien machine... and to damage his mentor, it must have been absolutely huge and powerful! The lunar dragon was too wounded to continue on; her death was inevitable. But she instructed her adoptive pupil to carry out one final task, to thank him for his companionship and set him on a greater path. She spared a few drops of her blood and told him to drink them during the next full moon, before breathing her last.
Heartbroken, but respectful of his teacher's dying wish, Bret ingested her blood a week later during the full moon. Doing so transformed him, granting him strength, insight, and magical ferocity the likes of which he could've only dreamed of; he was now part lunar dragon! Gifted with this might, and determined to see his teacher avenged, Bret set out to travel Numeria. His singular goal: to find and destroy the machine that killed his draconic mentor, and make those who used it pay for their foolish mistake!
