The Witcher: Outcasts was a planned add-on for The Witcher that was in development by roXidy.
Outcast was going to be released as DLC in most countries and have a disc release in some countries, like Poland and Russia. It was in development from late 2007 until around mid-2008, when it was canceled by CD Projekt RED.
The story takes place in the early part of Geralt’s life, before he is established as a Witcher, during the reign of King Videmont of Aedirn (around 1190). It takes place in the Skellige Isles off the west coast, on an island ruled by jarl Harald. Many years ago, a monster attacked Harald’s pregnant wife Morganna. In return, Harald went out to slay the monster, with the help of the gnome Shiltzen. As payment, Shiltzen demanded Harald’s firstborn, but when Morganna gave birth, she bore twins. Seeing that the second child was monstrous, Harald gave that child to Shiltzen instead of the firstborn Astrid.
The full design document was originally posted at GameBanshee, but CD Projekt RED's law agency issued a cease and desist letter on October 22, 2010 forcing the site to take it down.
