The planets are living powerful beings and the sentient species that occupy their surfaces are their children. They face a crisis when their elemental lifeblood begins to seep into the children, eventually culminizing into a soulstone which gives them great powers, but at the cost of their life and eventually that of the planets’ too. One childless planet, Earthsong, is given the task of retrieving these children from their homeworlds and bringing them to her surface where they are safe. She is given tools made of Siderean, or star, element which allow her to remove the soulstone from its host and both back to their planet of origin. Visiting children remember little of their previous lives while on Earthsong and when they return they recall only glimmers of what occurred during their time away. These individuals often build up legends and myths around their strange and fragmented memories of alien species.
