Lustful Sin


There once was a strong demon with the ability to take control of other people’s thoughts and behaviors and utilize them for its own purposes.

The devil traveled the globe for thousands of years, causing panic and fear wherever it went. It was almost impossible to escape once you were entangled in its web due to the subtlety and potency of its power.

Ultimately, the populace banded together and shut it away, putting an end to its terrifying rule.

“This is the falsehood they propagated to their kids about you. “
