Polaris is the north or pole star and the brightest star in the sky, found in the Ursa Minor/Small Dipper constellation. In Norse Mythology the Pole Star is known as Veraldar Nagli or the World Spike, placed at the center of the universe and has the heavens revolve around it.
She is a godlike entity that resides in the Akasha Stratum, and has access to the Akashic Records, allowing her to edit the fate of multiple universes. She has inherited the Heavenly Throne from her predecessors, Kochab, Thuban and Vega, with Er Rai being her direct successor. This implies that Polaris is actually a member of an alien race, rather than a unique being.
