This is a great introduction module for Eberron and Sharn. Not much opportunity to explore Sharn but I did give the characters a good introduction to the City of Towers, the three levels, and the interactions of some of the magics, which take place in Sharn. I explained some of the differences between Faerun play and Eberron most notably the aircraft of all shapes and sizes, the mechanical contraptions moving about, and some of the characters one could run into around Sharn. I did not provide a backgroud history to Sharn, not enough time to do that in a 2 -4 hour module.
For the actual play the characters and I were a little confused with the ariel assualt between the two ships specifically when they moved from one ship to the other they find that EVERYONE is dead, which was hard to explain, I mean just seconds ago you were fighting and then just the ZERO pre-gens survive, what?
I did have them encounter one patrol (bandit capt and three bandits) and every character went to 1 or 2 hp in the first round, that's after I downed the stats on the four bad guys. Luckily Xen the shipwright and Sivas the gnome intervened and helped the players escape if not they would all have died.
I enjoyed the ending, I opted for the automatic crossbow mount to intervene after the bad guy threatened the players on the ship.
Overall a good story, might need a little tweaking to give the DM a better explination on the ship to ship combat and results of the crew.
Cannot wait to run more Eberron story lines.
