An ongoing series of modules for the first Neverwinter Nights game detailing the adventures of the bastard nephew of the Count of the fictional County of Kosigan on the border between the Duchy of Burgundy and France, in a fictionalized version of fourteenth-century Europe with some magical elements. The series consists of six modules so far, five of them already have translated from French.
- The Slandered Lions ("Les Lions diffamés"): A prequel and untranslated episode set right during the beginning of The Hundred Years War.
- Exile of the West ("Exil à l'Est"): The Bastard, leaving an uncomfortable household after his father's death, travels to the city of Koln in Germany and walks into the middle of a conflict between a coven of witches and the sinister Inquisition. More of a prologue than anything else, this module has little direct connection to the remainder of the series but foreshadows several important plot elements.
- The Bastard of Kosigan ("Retour à Kosigan"): The Bastard, returning home from his adventures in Koln, is asked to rescue his childhood sweetheart Alexandra from the dungeons of the Duke of Burgundy, which leads to the exposure of a complex plot to destabilize Kosigan.
- Revelations ("Révélations"): The Bastard visits his mother's grave and learns dark secrets about the nature of history and religion.
- Blood and Tears ("Du sang et des larmes"): War breaks out between Burgundy and France, and Kosigan is caught in the middle.
- By the Word and the Blade ("Par le verbe et la lame"): The Bastard and his troops are now hidden in forest. They have few time to look for new allies for their struggle against France.
The Bastard's adventures have been placed in the Hall of Fame at the Neverwinter Vault.
A series of novel adapted from the mods is being written by the modder. The first of them is set before the events of The Slandered Lions and has been released in 2014.
The Bastard of Kosigan series contains examples of!!
- Black-and-Grey Morality: Everywhere
- Childhood Friend Romance: With Alexandra. It does not end well.
- Darker and Edgier: Probably the second-darkest story to come out of the Neverwinter Nights toolset after A Dance with Rogues.
- The Dog Was the Mastermind: In The Bastard of Kosigan, the real mastermind behind the whole plot happens to be Alexandra de Velan, your childhood sweetheart, who also happens to appear to die near the end of the second module.
- Heroic Bastard: The protagonist is one.
- Historical Fantasy: The series is set in an alternative version of medieval Western Europe with magic and standard fantasy races.
- The Hundred Years War: The series is set in the first decades of it.
- Kick the Son of a Bitch/Kick the Dog: Zig-zagged with the death of your cousin and his wife and preteen son at the hands of Alexandra in revenge for her brutal treatment at his hands.
- Lawful Stupid/Chaotic Stupid: Invoked by the modder. The description of the episodes warns that following one of those two archetypes wouldn't probably fit well the game.
- Luke, I Am Your Father: Count Borogar's ghost to the Bastard. How you take it is up to you.
- Optional Sexual Encounter: There are several of them in the series. Not only they are totally optional, but (contrary to the infamous A Dance with Rogues) the few sexual encounters with actual plot relevance allow the player to skip the explicitly sexual description.
- Orphaned Series/No Ending
- Prequel: The first episode of the series ("The Slandered Lions", not translated in English and set before "Exile of the West") is the latest released.
- Videogame Cruelty Potential: Some over-the-top choices are available.
