The uninhabitable, cursed land where strange black trees bleed under the crimson sky.
Ishuella is an abandoned place that has been isolated from the outside world a long time ago by the Tower for an unknown reason. The sky is crimson because of the Tower’s barrier. It may be possible to use a high-level teleportation circle in order to get through the barrier and allow access to the area. The demons appearing in Ishuella is still a mystery.
