The Obsidian Order

The Obsidian Order is a group of followers of Brumbarr that aim only to become rich, they will stop to nothing to strip the earth for anything of value.
Each one of the leaders of thos cult is filthy rich, but it's never enough; they use slaves to mine menerals and gem, forcing them to exhaustion to quickly extract all the valuable materials before abandon the mine and begin with the next one.
But this is not enough, they buy, steal and cheat to acquire art objects, unique items and magical treasures. What they acquire they will keep hidden away and only they will see it ever again.
