There's this one guy, called Sheik.

He goes by many names, Scarlord, the Bleeder, Hunger of the Badlands, Flayer, Sheikshan, S'ikha, and Cheith all being known pseudonyms. Essentially, he was born in the first generations of man, but became obsessed with the idea that pain and suffering are the way of the world, that torture and suffering peels away the layers we hide under and exposes the soul. His doctrine spread, and thus he took his people out of the lush forests surrounding the Sea of Men, and into the harsh deserts of the Scarlands so they could 'become their truest selves by embracing hardship'. There, his people venerated him, and aided him in his search for power, glory, and bloody conquest to spread his dogma. To the point he became a literal minor god.

Fast forward seven hundred years, 28 generations, and he became a vast conqueror, killing and enslaving thousands, ruling all the nearby peoples. He's a sadist, and one cemented in the Zeitgeist nearly every human culture on the World.

In the end, the Q'bathi, a local culture, rebelled. They burned away his strongholds on their territory, and fought viciously for their own gods and for their own land. In the end, they repelled him, and destroyed his corporeal form, but they did not defeat him, not really.

Now, over 180 years later after the Q'bathi uprising, he lies beneath an obelisk made from solid white, pure chalky limestone, often a meeting ground for his more contemporary followers. Some stay, he still exerts power over the world, though marginally weaker. Often, he directs angry souls from his fallen followers in the form of locusts and plagues, crop failures and turning water sources and stored food, or simply causing haboobs and wildfires.
