The Northlands Trilogy and Beyond
Realms of Arkania: Blade of Destiny was the first game in the trilogy, it was followed by Realms of Arkania: Star Trail, and Shadows over Riva. As a feature players could save after beating the game, this allowed players to import their characters into any of the sequels. The next game set in the The Dark Eye-universe was Drakensang: The Dark Eye (German: Das Schwarze Auge: Drakensang). However Drakensang is not a continuation of the Northlands Trilogy storyline and it is not possible to import characters saved at the end of Shadows over Riva.
