These beasts are a riddle wrapped in a mystery inside an egg. Deep within each shell, cradled by wisps of shadowy darkness, are living yolks of shimmering light. Throughout their lives, these creatures grow, evolve, and mature within their protective shell. Until one day, the light and darkness merge into something mysterious and alien. While no one has any clue as to the origin of these egg-bound beasts, it is rumored that they are not native to the islands, nor even this world.
