The room is a relatively small room, with a really ugly two-tone paint job (white and brown) and some exposed pipes on the right (facing the back) side of the room. There is a small, spartan bed, made up with white bedding, and a small, cheap writing desk in the corner. It is comfortably warm.
It is an evergreen forest, thickly grown with deep bluish-green trees. Everything is at least somewhat moist, and there is a bright, verdant feeling to it.
The path is narrow, but well traveled. There doesn't seem to be any markings or obstructions, and it winds (as opposed to following a straight line) through the forest.
The water is a small stream, relatively deep and quick-moving. The water is clear, and very cold - it is a high elevation and the water probably came from mountain meltwater.
The small bottle is earthen, very simple with no design. It is round, but it tapers to a neck and then curves out again for the mouth.
The key is old and rusted, and is of the very old variety that is a shaft with one or more little rods coming off it like so. It unlocks a small hut made of stone.
