The outline of....trees?

The blue light only extends in a radius of ten feet or so in each direction. He would have thought that to be enough to illuminate a room in this maze, but apparantly this was larger. He mumbled another few syllables, extending the flare another twenty feet in each direction.

The light still failed to reach walls, but now he was sure, the large objects it illuminated had to be tree trunks. Either someone placed trees in the room, or the door had more to it than he had expected. He turned to examine it, half expecting to find it as part of a wall. Apparantly it was no such thing, the door simply rested upright on the ground.

He pushed it tentatively. It didn't budge. He moved around it, studying it slowly. It was simply a door, only the back didn't have a handle. He scratched his head, then decided to head on through the unaturally dark forest.
