Pyre was an Ancient Red Dragon who took up residence and rule of Mastwick following the start of the Demon Apocalypse. In exchange for destroying the larger demons that menace the city, Pyre would collect a tribute of gold and rubies from the town. He used his power and influence to continue his rule after the Demon Apocalypse ended.
He sent the then un-named Ätlän-tã Fælcons on a mission to collect four Slaad crystals once. They were trapped in the city and there was no way out except for with his permission. It was a whole thing. They did that, and he let them leave. Much later, Pyre attacked The Monastery of Uthgar in Ssathra, with the aim of collecting The Orb, a powerful, god-killing artifact, but it was taken by The Tower of Grey before he could get it. He then became a target of that group looking to capture powerful and evil creatures throughout Drunkeros, as a way of making ammends for their recent transgresions. And also, for their game of Bones.
