This was the place that the deities met to stop a cataclysmic event from happening. The gathering of divine energy still effects the area today, making it a true holy ground. This ground is in Felmentua, which is what the city was built there for. The holy ground emanates so much divine energy that people adept at magic are able to easily focus their skills to create a magic item. This divine energy also helps keep the force walls up, so it contributes to its own safety.
