Darkwood oven

A pleasant warmth is emanating from the oven. I can sense a strange, yet familiar scent. It's the smell of the "protective substance", which gives me relative safety after dark. The vapors rising from the huge cauldron are distributed all over the house via long pipes. As long as i remain inside my hideout, I have a chance of surviving the night. When i arrived here a couple of days ago, the oven was basically prepared. I just needed to light it up to ensure my safety at night.
