Book of Friends and Foes: Assassins in the River Nations
This roleplaying supplement provides eight fully developed assassin NPCs for adventures in the River Nations. Covering character levels 6–14 and a range of classes, the assassins include rogues, witches, rangers, clerics, fighters, bards, and a magus. Each can serve as a recurring enemy, source of plot hooks, or deadly threat during a kingdom-building campaign. A Hero Lab file is included for quick integration into the game.
