We are using the current rules set for C&C, which is 5th Edition. We are playing in the Kingdoms of Kalamar campaign setting, which is just pretty much the best one out there.
We started in the year 563 Imperial Reckoning, which is where the box set / books for KoK mention would be a good starting year. The players are down in Tarisato, which is south of the main country of Kalamar.
Our players are Sir Erwynn Erodarr, a LN Human Knight, Lyanna of the Shadows, a NG 1/2 Elven Ranger, and Baylan the CG Human Wizard.
Sir Erwynn is Sir Erwynn, Lyanna is Black Diamond, and Baylan is Baylan. Your Castle Keeper is Shadowhawk.
