Once out in the wilderness, the humans of the city were no longer a threat.
However, for Hao Ren and Lily, the ancient armed forces in the city were not a threat. Without the two of them, the group of witches with their limited mana and mortal bodies could face grave danger.
After they left the city, Witch Helen summoned a couple of Shadow Horses. The gloomy weather had done the witches a big favor; the shadowmancy spells worked like a charm even during the day, allowing them to leave the city's area of influence and get away from the exorcists' peering eyes. After traveling half a day by horse, they returned to the stronghold of the witches in the foggy cemetery at sunset.
The permanent fog seemed to be an unusual phenomenon. Without the witches' guidance force ordinary people could never get close to the border of the fog. So before the demon hunters found it, the cemetery was a safe place.
