Their high hopes crumble when the expected deity crashes and is destroyed by a large beast called a "plllnk". As more gods arrive, each meets the same tragic end, exposing their weakness. This leads to a major shift in the beliefs of the Phobos inhabitants, who realize that their gods are not as powerful as they thought, changing their religious views forever.
