Drow

Dark Elf, also known as Drow.
This species lives in the darkest corners of the world, since they have long ago been cursed in the eyes of the sun.
Their hatred towards the elves is well-known, but the reason for this conflict is less known to the inhabitants of the countless worlds. During the The Tyranny of Obran , they fought at the side of Obran The Tyrant against the Sun Elves loyalist. At the The battle of Imeth Dorei, Tordril unleashed a cataclysmic spell upon the infernal drow. Forever more, the drow were cursed and debilitated wherever Lathander 's light would shine. 
Whenever the Drow invade the surface, it is often at night. These raids sparked great fear and numerous cautionary tales about being alone on the road at night.
