God's Sanctum

Thirty years ago, a beam of light shot up into the sky. With its appearance came the emergence of the supernatural that the world had long since forgotten.
Beasts of yore have resurfaced, and intend to overrun humanity, but they are limited by one thing. The Sanctum.
The Sanctum, also known as God's Sanctum, has been upholding its role of suppressing the supernatural forces of the world for time untold, but now, it is weak, and there is no one to reinforce it, which has lead to the reemergence of the supernatural.
