The wights have taken Sharn. The PC's wanted to do something about it, and I don't care to much for A Gathering of Winds. I have about 50% of the write-up for the replacement adventure complete. I need a map, even if it is from a pre-existing adventure of a 3-4 floor building/structure. I can modify it as needed. Any suggestions?
The Wizards website has TONS of archived maps available. I'd look there.
