Varis

Varis the Virulent, Cleric of Death, is the leader of the Vampire and former Cleric of Life, servant of Lathander. Varis' alignment was changed from Lawful Good to Chaotic Evil by The Die of Many Things.

History
Varis was a core member of the Lightbringers, the group that liberated much of the afflicted regions in the Scar, amassed an intimidating army of powerful creatures and dragons, and ultimately stopped the tyrannical lich Gregg from plunging Toril into the Abyss. The legend of the Lightbringers says that Varis' gift of life could restore even the most grievously ill or injured creature to vibrant, blissful health in an instant.

On the final stretch of their campaign to close the ever-expanding gate between the Abyss and the Material on Toril, Varis, Fred, and Emrick Il-Khan flew to the Moonshae Isles in pursuit of a mysterious source of chaotic evil power. It was there that they discovered the Die of Many Things. Emrick was overcome by the Die's fateful gifts, and rolled it repeatedly until he vanished.

Varis and Fred soon learned that Emrick was gone, though his body remained. An old, evil entity known as Dorn possessed Emrick's body. When they destroyed Dorn, Varis retrieved the Die from the corpse. He cast it into the sea to rid the world of its temptations. The Die rolled on the sea floor, landing on a side that would change the fate of both Varis and Faerun. The Die changed Varis' alignment from Lawful to Chaotic, from Good to Evil.

Varis secluded himself in a nearby tower-city, which he cleared of its residents and established a throne on top of. From there, he would begin his reign as Varis the Virulent.
