"A spiritual attendant to humans in Norse lore. She is known as a goddess of both farming and war, though some see her as a low-ranking servant of the valkyries."
A trio of non-recruitable Disir appear in Sector Bootes. They used to possess time-based powers, until the rampaging Yggdrasil stole them for his own benefit and empowered himself as a powerful monster with full mastery above time, giving him the ultimate edge in battles. Desperate for help, the Disir encountered the Protagonist and convinced him to attempt to destroy Yggdrasil, teleporting him to Sector Eridanus.
The Disir were, however, confused to see a second version of the Protagonist pop up just as soon as the first one had been nearly killed by the rampaging tree; at this time, the sisters' combined future form, Norn, cancelled the stolen powers, removing Yggdrasil's edge and leaving him open for a counterattack. Realizing they were meant to eventually reach the power of Norn and send the Protagonist into the past with their restored powers, they sent back the past Protagonist to Bootes with no memory of the fight and rewarded him, instructing him to remember he still yet to destroy Yggdrasil for good before the ontological paradox was completed and the loop closed.
