You can get some light down the cave by setting one of the dead wolfmen on fire, which offers plenty of illumination as the cave itself opens up from the light. Show casing plenty of luxury cave features, like a semi dry floor, a lack of freezing wind, and deeper areas to trek down in and get away from the horrible weather. The further down the cave shows off more unique and interesting smells, along with basic furnishings and provisions that the wolfmen were using to stake out the mountain road for evil doers such as yourselves.
