what you do, is have the druids go into the town and offer a warning, that because of the wickedness of the townsfolk the Gods themselves will destroy this town and anyone who remains in it. doesn't matter if anyone believes them or not, as long as a lot of people hear it, and make sure it's memorable.
tell them that their wickedness stems from a refusal to honor nature and it's place in the world, that their civilisation and all others will be called to judgement.
the next time there's a big festival on, wait until a high point in the festivities, preferably at night. a storm brews up (control weather) and it starts to rain heavily, wind comes up, etc. lightning starts hitting random people in the crowd (call lightning), the storm intensifies (storm of vengeance), the ground starts to move (earthquake), the heavens themselves rain down fury (storm of elemental fury). all of this continues for about 2 minutes (an earthquake centered on the festivities every 30 seconds, and storms of vengeance and elemental fury going off a couple of rounds since the last one finished, call lightning in between, etc)
The storms created by call weather cover the entire town and last until the townsfolk decide to abandon their homes and leave. the continual rain eventually floods the water supplies and the sewers mix with the drinking water, causing all kinds of diseases. everyday random storms of vengeance and elemental fury occur in places of "wickedness" and earthquakes are constantly affecting the walls of the city, places of worship, major trade districts and any nearby dams. also, the occasional tornado doesn't hurt things, neither does the odd cometfall to take out pesky priests, or members of the townguard.
the druids come in from time to time to call the town to judgement, and tell them that they must flee to escape their fate. once they have left, they must repent their sins, or the destruction will follow them wherever they go.
in regards to secrecy, the dwarven stonelords use their meld into stone ability to hide, then they use their earthquake ability, easily able to make the DC18 fort save to avoid being destroyed if worst comes to worst.
the dwarven stormlords use their wildshape ability to turn into eagles, then fly amongst the storms, being immune to lightning damage and not all that worried about rain and hail, etc.
once this has gone on for about a month or two, if there is a city left, i will be surprised.
most people abandon the city from the disease and panic, lack of clean water and constant threat of earthquakes. the few die-hards that remain can be easily cleaned up with a few lightning bolts. once the town is empty, just keep using earthquakes and other things, including cometfall.
presto chango, no more town, and odds are that it will be cursed by the priesthood who were kicked out of the town, no-one likes to admit defeat.
on top of that, the experience you get for detroying the town and all the people should see you get enough experience to level up significantly, so you can continue to do it again and again, in bigger and bigger cities.
mwuhahahaha
