Aleema Keto fabricated illusory space grazers.
Space grazers represented mythical, enormous space-based organisms that, according to legend, hunted spaceships. It was widely accepted that they had died out millennia before 4000 BBY.
In the course of the Battle of Koros Major, Aleema Keto manifested a magical illusion depicting space grazers. Her intention was to undermine the morale of the Galactic Republic fleet positioned above Koros Major.
