OK, thanks for the advice. I have read through the 1st three chapters but had only skimmed the rest so I thought I had better check and make sure it wouldn't be a problem/pain later on.
Yes, Zenith and the Malachite Fortress would be good tie ins. I also thought of changing Phalian Gurnezarn of Gurnezarn's Smithy into a dwarf from one of the characters clans. That might give them a vested interest in the town and extra motivation to save it. It might also add to the tension between the Stormblades as it is the only non-Lathenmire smith in town.
Any other advice out there for a DM on his 1st time through SCAP?
