For me, Sword of Selfaril is a good adventure. It has a nice hook that introduces you to the scene and backstory. The characters are thrust into a scene where they are forced to fight and then they figure it out afterwards what is going on when an NPC shows up to talk to them. The adventure is made in a way that if they do have the item needed a different scene occurs. If they don't then the scene is similar to if they do have the item needed. In a way this can be run even if you haven't done the adventure prior to this one. The roleplay opportunities here are within the city when talking to the different factions and convincing them to support your cause. The final combat is fun because it is an all out brawl with the key NPCs fighting amongst themselves while the characters would be dealing with others wanting to interfere withthe NPCs duel.
