Skeletons of Scarwall (3e)
The heroes have learned the identity of the evil that plagues Korvosa - the vile remnants of an evil dragon who once ruled much of Belkzen as a sadistic warlord. In order to defeat him again and save both Korvosa and the queen¸ the PCs must journey deep into the orc-held lands of Belkzen and brave the haunted reaches of Castle Scarwall¸ once the dragon's seat of power. Somewhere deep inside waits the holy weapon Serithtial¸ the sword responsible for his defeat hundreds of years ago. Only on its edge can the dragon be driven from the world.
