Dewport, once the biggest human City in the West of Deireadh, got destroyed during the Gruama Forest Battles against the Elven Army. This resource conflict ended with the Elves claiming the formerly human governed South leading to the deforestation and resulting desertification of the area. This inter species conflict revolves around coal that's needed to fuel steam engines. While humans turn towards the hard coal mined ind the Silab mountains. Elves view Forests that are not part of their native ecosystem as replaceable and clear large areas.
