The Legend of Blacksilver is a fantasy adventure game which is an indirect sequel to the game Legacy of the Ancients.
The principal character in the game is first contacted by Princess Aylea in a dream-vision. They are told that the evil Baron Taragas from the Kingdom of Maelbane has conspired with a local baron, Baron Mantrek, to find a magical material called Blacksilver. Supposedly in the hands of evil, Blacksilver could be used to create weapons of mass destruction. Princess Aylea instructs the character to rescue her father, King Durek, who has been abducted by Baron Taragas.
