Red Mountain is a volcano located on Dagon Fel. It first erupted during the Age of Continents, and it erupted a second time marking the end of the Age of Ruin and beginning a new Age of Darkness in the world. This second and more devastating eruption was prophesized for many millennia to be the catalyst of a new dark age upon the world which would be the end of all living things.
During the Age of Ruin the volcano finally erupted, putting an end to the age and all life on the continents. After which it’s influence continued to spread, just as prophesy foretold.
