The first 90% of the adventure consists of the PCs traveling along a road after Lucan, fighting random monsters. If the random monsters get too boring (And they do), the adventure suggests throwing in a less-random monster in the form of mysterious NPCs literally described only by name. A quick look at the map shows the road takes the PCs through a town, but neither it nor Lucan's passing is described anywhere. Neither is Zilargo's book description of being peaceful and monster-light honored in the adventure when the PCs face 1-2 deadly encounters per day of travel (Enough random monsters to level up at least once), none of which have anything to do with the adventure.
After the first encounter with Lucan, chances are his coach is destroyed. That means he has no shelter from the sun and is still several days from Trolanport. Grilsha's wand can keep him safe for maybe half a day before it runs out of charges, and Lucan dies.. and yet, the adventure expects Lucan to not only reach Trolanport but to beat the PCs there by significant time. Other vampire weaknesses/immunities conveniently forgotten are homeland soil required to sleep in a coffin (At least twice), and immunity to mind-affecting effects.
At the masquerade, Neya opens up to the PCs and tells them that she gave Lucan a password to get onto Cloud's Destiny free. Of course the very next words out of the PCs' mouths are going to be "what's the password", but the password is not given nor is its existance accounted for in the next chapter. Instead the PCs must fight their way on board, bribe the captain and accept being turned away at every attempt to find Lucan. It's a wonder the adventure didn't end with the wholesale slaughter of the crew.
Next Garrow steers another airship into Cloud's Destiny, wrecking both presumably over frustration failing to capture Lucan. He apparently survives given his appearance in the next adventure, and yet he ceases to chase after Lucan or the PCs at this point, content to have just wasted two weeks of time, an airship and dozens of soldiers.
After the airship is a very similar lightning rail scene which has nothing to do with the story save that Lucan is somewhere on the train, completely undetected. I skipped this one. I also trimmed back the ziggurat because I was tired of inconsequential random encounters and wanted to end the adventure.
