Starsquid are the only known creatures that live in the upper exosphere. They are translucent floating jellyfish that hunt on moonless nights by using their bioluminescence. When dawn comes, they ascend back into the heavens to spend the day resting and digesting.

Starsquids are said to be ancient and wise, and are responsible for inspiring mankind's first attempts at flight. According to mythology, they originated as energy life forms in the early days of the universe and slowly drifted through space until being captured in our planet's gravity well.
