Hey, for all you modders out there in need of a fresh idea. What about a mod where there is a NPC in Markarth, whom you can bring dwarven scrap artifacts as well as dwarven oil. as you do this, more of the Dwemer's old gas lamps start to light up in the buildings, until the entire town is lit by them once again.

Also, as the lamps come on in the buildings, the inhabitants remove thier crude, Nordic candle lamps.

After all the lamps are on, you can bring him dwarven oil, for which he will pay you a fair ammount of gold for each. Since the lamps would use dwarven oil as fuel.

This mod would also have to change the lighting in each house as it is restored, so the light sources come from the gas lamps.
