Prim Picaro

(a.k.a. The Magpie)

There are lots of draconic deities, but the "god of dragons" title is jealously guarded by a single individual.
As a mortal, Prim Picaro led the first group of dragons to Agrophon. He was a beloved leader and soldier who was deified less than a century later. Picaro's species and ancestry are unknown, having been variously described as a metallic dragon, a chromatic dragon, and other rare or even mythical species. Picaro has dozens of divine aspects, taking many different forms and resplendent hues.
Prim Picaro's name is sometimes humorously translated as "the fussy rogue," but this isn't quite accurate. His original name, Primus Picaro, is more severe.
Developments - Act I

The big "creator gods" have learned to be extremely careful with their incredible power. Picaro is an exception; after centuries of practicing his strange and powerful skills on the Feywild , he decided that he's talented enough to be a more "hands-on" deity. Starting in 702, he happily uses his powers to benefit mortals, so it can be tempting to pray for his help. His only ability seems to be turning things into dragons, but he never gets bored of it.
It's common knowledge that summoning Picaro is a bad idea, but most people don't know why anymore. The stern warnings from local dragons have diluted over the years.

Developments - Act II

During the war, people started to talk about Picaro again, and the vague rumors and superstitions around him gathered strength. Picaro's dragons are treated with suspicion. Why is it so taboo to summon them? What are they planning?
Picaro refuses to clear up the misunderstanding; after all, his foul reputation is his own fault. Behind the scenes, he's incredibly disdainful of mortals, especially the ones he creates. Sometimes he'll conjure a paper dragon, scribe a message on it, and send it to its destination; as an afterthought, he'll give it the ability to speak, a complex brain for processing commands, even some hopes and dreams; and he'll rig it to burst into flame as soon as the message is delivered. Picaro is too powerful for his own good, twisting and destroying lives without seeming to notice.
Picaro's monstrosity was discovered a long time ago, but people keep forgetting why it's so wrong to call on him for help. After all, it's usually his own creations who suffer. And history remembers him as a good and pleasant deity--he became craven very gradually, and it took even longer to notice.
