You were only a few dozen yards away from Your Cabin, which sat atop the hill, the lights from inside clearly seen through the brush and trees of the woods, which gave you a point of reference if you need to return, while it wasn't night, the sky did dim a little, which made everything have a dark undertone to it.
As you kept your march through the woods going, you saw a slight clearing of trees, in that clearing the leaves looks odd, gray and brown, while it was late summer, You'd never seen trees lose their leaves to early this time a year, drawing closer to the clearing, you noticed the trees on the edges looks either dead or very sickly, with very few normal colored leaves, if any at all.
Once in the clearing you took notice of one thing, a dim glowing green beneath the leaf covering, as You approach you notice a bit of rock poking out from the leaves, you swipe your foot around this area to move the leaves aside, to reveal a large chunk of rock, with odd dim green glowing gemstones jetting out from the strange object, You step back, shocked, but semi intrigued..
