Metaphysical / Paranormal event
Broken and worn down by over a century of slavery, the pleas of the enslaved finally reach the ears of someone who might help.
Since their intrusion into Gyrraholm, the Drachromatic Bereich had shown no mercy to prisoners taken during conflict. The slave trade is not a common one in Gyrraholm, but this Chromatic society was steeped in it, since the early days in their own plane. Depending on who you speak to, the stance on slavery is what split the dragonborn nations to begin with. But for over one hundred years, the Chromatic forces had been accruing slaves from around the world, assisted by their Minotaur associates, and it had reached a boiling point for the humans of Valoreign, the first victims of the Chromatic expansion. Outnumbered and ill-equipped, there were few things that could have changed the fates of these slaves, but one who delights in making deals with those in poor bargaining positions heard their sorrows from across the planes. One cold morning Asmodeus, the Lord of the Nine Hells appeared in the largest slave quarters in the city before a crowd of weary humans, offering power and freedom. In exchange, he would reap their souls when life had left them, and the mark of Nessus would taint the descendants of this pact, forevermore. Desperate, a deal was struck. The Humans who were willing underwent hellish transformations, growing horns from their heads, tails from their spines and even hoofed feet in some cases. They overpowered their red dragonborn guards, alongside a flood of devillish fiends who assisted in the escape, and while not all of these former Humans escaped, a majority would, marking the beginning of the Revolt of the Flaming Bonds.
