The first thing I notice is yellow. Then I notice my feet are cold. Burnished gold carpet, faded yellow wallpaper, a desk, a chair, a window. I think I may be in a basement.
The trees are short and scrubby and the underbrush is thick. The sunlight filters through the thin foliage on the trees and feeds the ground.
The path is primarily discernible by its lack of trees. The undergrowth has concealed most of the path, but it is barely visible through the plant life.
I see a stream. Although it would be easily forded (I could probably do it without getting my feet wet), it is well-fed by small local springs. The water is clear and cold.
The vessel is small and made of red clay. It looks somewhat like a Greek amphora, but without decoration.
The key is an old brass skeleton key, turning green in the dirt. Perhaps it unlocks a nearby cellar or toolshed.
