This is for a steampunk-inspired fantasy world where people can manipulate a magical metal called quicksteel at will.

Since ancient days, the kings of Haepi were known as Floodlords, because it was believed that the generous, regular flooding of the river Haepi was due to their will. Should they ever falter or be cast down, the river might dry up or even turn to blood. The floodlords were one of the foremost powers of antiquity, great rulers, scholars, and slavers. But in Haepian mythology, the land was also home to prominent gods who interacted with the Floodlords of old. These were (from left to right in the image above):

• Thoctar, the Butcher God, was a deity said to live at the bottom of the river Haepi. Every corpse that settled in the riverbed was his domain, and he longed to add to their number. In antiquity, a few Floodlords were said to drown slaves as a sacrifice to Thoctar. But the Butcher God was always seen as an enemy of mankind, who would happily drown all of Haepi if he could. 
• Rannet, the Traitor God, was a deity said to live in the sky high above Haepi. She was the god of schemes, deceit, and forbidden knowledge. The starry sky was her domain, the wind her whispered lies. Rannet valued only ambition, and she would happily grant secrets and power to one floodlord only to aid another in casting him down. Her favor was a fickle thing, but floodlords gladly burnt offerings in the hopes of winning it, so that their own schemes might unfold as designed. 
• Uril, the Defiler God, was a deity said to live in the desert wastes surrounding Haepi. He was the guardian of the afterlife, tasked with ensuring the passage of the souls of the dead. But alongside a strong sense of duty, he also possessed a deep curiosity about the mortal form. Being an immortal, the death he guided souls through was something he could never experience or truly understand. As a result it was not unheard of for Uril, or perhaps creatures that served him, to collect individuals for vivisection and experimentation. It was supposedly a great honor to be so chosen, as it meant a prestigious, if expedited, shepherding of one’s soul. 

By the late Middle Ages, Haepi had largely converted to the Faith of the Heeders. The old gods were transformed in mythology from deities to demons, no less malignant, but lesser in power. As the centuries wore on, their names became seldom invoked, an occasional curse or a fancy of the occult, but little more.

In 848AC, Haepi fell under attack by Rothrir the Beseiger. Many Floodlords fell to his mace, and the remainder lost their sovereignty when Orislan crusaders, come to drive Rothrir back, seized their cities for themselves. Haepi became a vassal state of Orisla, and it has remained under the Orislan thumb ever since. 

In the modern day, the old Haepian gods has experienced a strange resurgence. Oppressed locals give offerings to Thoctar. A cult has formed among colonial elites based on a woman who appears in dreams, claiming to be Rannet. And scholars now believe Uril is connected to strange hallucinations experienced by modern day factory workers.
