"The party enters the Vault of Dragons, and discovers the hoard already plundered! Not a dragon stands. Where is the gold?!?! The Villain has already stolen it, but they still need to get it out of the city, down to Skullport. We have intel that they are hiding it in a number of the floats in the upcoming holiday parade. There will be hundreds and hundreds of people there, City Watch, and the Magister overlooking all of it. The Magister has been paid off by the villain."

"...We have to set up a heist to steal the gold before it gets to the end warehouse where the entrance to Skullport is. If they get it there, those dragons will be lost forever. Let's start planning."

What do you guys think? This is the most tense and Heist-movie-like ending I can think of. What ideas do you guys have for this???
