In 2023, a wider audience was introduced to the world of Forgotten Realms in Dungeons & Dragons: Honor Among Thieves, but the film has only scratched the surface of the world's countless villains that could appear in a sequel. In the film, Edgin Darvis and his plucky crew embark on a light-hearted romp through the Forgotten Realms, one of the most famous settings Dungeons and Dragons games are played in. The party honors the time-honored tradition of going up against a nefarious overarching villain, typically referred to as a B.B.E.G. by players, standing for Big Bad Evil Guy or Big Bad Evil Gal.
