It has stood alone for countless years, but now the Lighthouse finds companionship in a curious and spirited seabird, who encounters the Lighthouse while seeking refuge from a creeping malevolent presence spreading throughout the isle. The Lighthouse discovers that its bright beam of light is able to affect the flora and fauna, and even seems to ward off the withering tendrils spreading throughout the world around it.

Meanwhile the bird proves to be a useful and dextrous ally, able to interact with strange and ancient mechanisms. Together, these two unlikely friends set off together on an epic adventure, an odyssey of mystifying metamorphosis, and a journey that will take them into realms beyond understanding.
