Yeah, I ended up using the Vessel of Stars from WotC. It actually worked out reasonably...though I think the lack of players (only 3 players) hurt it a bit. The adventure hasn't ended yet, so I'm leaving it for next week.
One of the things I noticed since coming back to play, is that I hate, as a DM, having to look up every minute something or another that is system-related. What is the bonus for flanking? How much concealment do I get here? What about cover? How many feet am I away? And then I have to look up monster stats in every fight...look at their resistances...if the NPC is a spellcaster, I have to decide which spell he will use, what the DC save will be.
Honestly...all I did yesterday was jump from DM's handbook, to player's handbook to monstrous manual the whole adventure. I should just memorize all the rules.
