It is a warm room. There are white walls and a steel table in the middle.
There are big sequoia trees. It's a thick forest, but sunlight can shine through.
It is a rough dirt path that winds up and down between the trees, around bushes, etc. It is hard to navigate but intriguing because it's hard to see.
It's a cold river flowing over rocks. The water is very clear and imaginably cold.
It's a small canteen.
It's an old brass key that looks dirty. I would imagine it unlocks an underground cave where elves live.
