Tola Forest

Tola Forest (トーラの森) is a vast forest that spans across Dilhade and Azesion, effectively serving as the border of both countries.

History
When Azesion and Dilhade declared war against each other, the Tola Forest was the unavoidable battlefield due to being the border. However, before the two armies could meet, Anos and his allies crippled the Dilhade army to prevent the war from starting.

Since he didn't find Avos Dilhevia at Ayan Hill, Anos teleported to the Azesion side of the forest and found him there. Anos immediately used Beno Ievun to enclose the area, isolating himself and Avos so he could confront the latter. Avos was revealed to be Anos' friend and also his rival from two thousand years ago, the Hero Kanon.

Although Anos was able to make up with Lay and end the war peacefully, Jerga is resurrected and turns the forest into a battlefield once again. In the end, Anos and his allies defeat Jerga without any casualties.

Ayan Hill
Located further west from the forest, on the Dilhade side of the border, the hill was where the main demon army encamped at. Numerous demon king castles were built there, serving as the headquarters of the army.

Grassland
Towards the Azesion side, there is a large section of grassland devoid of trees, which was described as if there was a hole in the forest. This is where Anos confronted Lay about being Avos Dilhevia.
