This is a fine adventure, although the roc battle feels a little too random, but it served its purpose well enough. It's an incredible follow-up to the Tomb of Annihilation since you can weave the plot from the Black Opal Crown right into it to make it a seamless transition the the summoning of Dendar. You'll be able to easily have the party get a rest in-between every encounter, which is probably recommended since the last fight can be absolutely brutal if they're not prepared. I played the Ramshackle King with the mannerisms of Sheogorath from Shivering Isles, which seemed to be a big hit.
