The dwellers of the Underdark invade the surface world
The near sunless conditions were the perfect opportunity for the Drow, and their underdark dwelling counterparts to invade the surface world. And so they did in 410 AGC the Shadow Wars began, and continued for the next 308 years as Drow armies marched on barely surviving cities. The Knosis hero Taurus Hornbearer reluctantly led his people’s armies once again against the Drow forces which threatened his beloved Asterus Isles. He would pass on at the age of 150 years in the Battle of Hornsend, named after the hero himself in the year 451 AGC. But he was survived by his Human Aasimar wife Arabella Songsword and his son. The wars with the Under-folk would continue raging into the next century when the clouds finally broke and the sun returned.
