Ananke is the premival goddess of compulsion, necessity, and inevitability. Showing that she is the goddess of compulsion and attempting to prove herself worthy, she declared that she was to stretch her arms across the broad span of the universe. Though that was not a good idea, and got her title completely ruined over proving her title. She and Cronus, the time lord and god over the Titans, were supposed to play a role of being entwined together forever across the universe too.
With getting her life and title ruined, she eagerly tries to find something else to do.
Ananke is a slender figure, often seen with a large bandages across her arms, due to the injuries of her attempt of stretching her arms across the universe.
