A massive meteor entered the atmosphere and scarred the planet over 5,000 years ago. As the giant rock passed overhead, milk curdled, livestock fell over dead, and ill fortune befell all. The meteor crashed into the earth with deafening force, and red radiance lit the sky for a week. Then it vanished.
The effects from the meteor still cover the crater it made. Very little vegetation grows in the scarred ground. Animals do not live there. Instead of healing, it seems as though the crater continues to cause more damage to the planet. The edges of the crater have shifted and grown into tall walls that are unscalable to the typical adventurer, and the only entrance is crossing the small lake in the middle. Though most would never want to venture into the crater anyway. Terror is rumored to rule here, evil and death and decay.
There is a mist covering part of the crater. More rumors of evil and death. Adventures who make it this far almost never return. The King no longer sends warriors to the crater, he simply attempts to keep the creatures on the outside of his wall. He is losing the battle.
Many clerics and followers of both good and evil deities have traveled to the crater in recent years but once they pass the kingdom wall, there is little information about what happened to them.
The Brotherhood seems to rule the crater, immune to the ill-effects of the crater. Nothing more is known about them.
