At the Nightmare Forest.
Nightmare Forest, it was said this forest is completely opposite of the Spirit Forest in the territory of Kingdom Hart. This is a forest that would sometimes emit demon miasma. The rumors say that a portal connected to Abyss can be found at the heart of the forest but unfortunately, no one has proved whether these rumors are true or not. Since like the legend of Ivern, the heart of the Nightmare Forest is forbidden land.
It wasn't as notorious as Ivern, which is considered as a dead zone. Nightmare Forest is considered as the boundary of the demon realm. There are countless magical beasts and creatures living inside this forest like goblins and kobold. Even high-ranking ones like dragons live in this forest which is why it was considered as the most dangerous hunting zone in the Aerd.
