A three part adventure for the Swedish role-playing game Drakar och Demoner Expert. The adventure follows the Archmage Vicotnik, his crusade against surrounding nations, and the player characters' attempt to stop it. The name of the series roughly translates to "The Nidlandic Cleansing", which is the name given to the Archmage's crusade.
The adventure has three parts:
- Helvetesfortet (The Hell Fortress)
- Melindors återkomst (The Return of Melindor)
- Sluttstriden (The Finale Battle)
The last part came as a box set and included a campaign book detailing the land of Nidland.
