The Abyss

The Abyss is generally referred to as "The Borderline of Threia". No one is believed to have ever set their foot on this land, but still, people believed that it exists.

The Abyss is generally a group of islands that has no vegetation. The soil is extremely barren and hard to the point that the color turned to black. Tons of poisonous gas and miasma covers the land. Even dead trees cannot survive the atmosphere.
