For the seed pod, sent off alone into the cosmos to help prevent creatures of the outer darkness from establishing a foothold on any planet, the journey is just beginning. Each seed is made of a durable, fibrous husk, and while most of the protective layer dissolves or is blown away in the journey, the seed's generative forces allow the larvae within to hibernate in the cold of space indefinitely until it either is destroyed by colliding with a star or inhospitable world or finally splashes down into a warm sea or lake where it can successfully germinate.
