This town has a lake and wells, so never really need water storage. They use buckets.

The gnomes, and everyone else in earshot (who isn't a PC and will make up their own minds) seem to agree that going to the temple is a good idea (or the only suggested idea and oh gods everything is on fire and those critters are everywhere ok lets go now to the temple you say?). The gnomes snatch of notebooks and grab crystals off of their instruments.
