A chilling wind whips through the hollow. Winter's bite grips your spine. The very air you breath stings. Snow swirls all around you, yet, the trees... the trees are motionless in the gale, unaffected by the cold, biting winds.
A large river that is continuously covered in a thick layer of fog. There will be either a rope ferry to get across or possibly a boat that is rowed across by worshippers of the water elementals. It is very thick fog to the point where it even muffles voices even at close range and visibility even beyond a foot is almost impossible.
