Into the Forest: Nature's Wrath

What happens when a young boy comes across a curious object that is considered real only in myth?
Sebastian is a twelve year old farm boy who lives with his grandparents. His father had left him there at a year old when his wife suddenly became ill and couldn't take care of them both.
Now, the young boy helps his grandparents till the land, feed and water the livestock, and bring home fresh meat from the surrounding forest.
It's this last visit into Kulgar Forest that Sebastian runs into a strange, green oval covered in spines, making him question this myth.
