Illusion Fog Barrier

The Phantasmal Barrier is a powerful barrier that seals off the entrance to the Land of Howling Demons. When activated it shrouds the area inside it in Fog.

Creation
The Barrier was developed by the King of Gwenbyer with the help of 3 Saints: a Saint of Mist, a Saint of Illusions and a Saint of Salt.

Seven Heroes
During a battle with Kyouma who were attacking the temple, Adlet entered the activation chamber only to discover that the barrier had already been activated by someone.

Function
With the power of the Saint of Illusions, the barrier makes anyone straying near the border turn back, keeping anything from entering or leaving the barrier.
