Belgos is a drow warlock from the city of Ched Nasad. He has traveled to the surface many times in search of knowledge about his powers. His most recent adventures have left him on the surface for an extended period meeting a dark knight worshiper of Shar that goes by the name of Roar. Roar led Belgos into the empire of Netheril, where they explored the ruins of Raveriss. In the sunken city, Belgos came across a black alter that radiated power. Upon laying his hands on the alter Belgos fell into a dream state. A voice came to him, offering all the he desired, power and knowledge beyond any he has ever dreamed of. Belgos agreed to this and to serve the voice in exchange for these promises. Belgos awoke to find his weapon had been replaced with a scythe of charred wood and a blade made of shadow and fire.
