Bright Lighting

Exploration Stage: Riverside Abode
From: Mayor
Description: The citizens are delighted that the garden of cherry trees will be lit in the evening. The lanterns should burn as bright as possible so that their light breaks through the fog. \n I examined a lot of illuminators and decided that we could use an oil lamp as well! Will you help me find it?
Completed: You’ve found a great oil lamp, it will burn all night. \n See this copper receptacle inside? A combustible substance is poured into it. I’ll prepare the lamp, but we need to make it before dusk.
