Stoer Kilos was a Force-sensitive living on the moon Rori during the Galactic Civil War. Roughly half a day before the Battle of Restuss started, he went out into the field to meditate and returned to find the city of Restuss in ruins, in the middle of the battle. Upon entering the city, he was met with a patrol of Stormtroopers who stopped him from going any further. Although he questioned them about his friends in the city, he was told simply that all civilians had been evacuated to the local space station and that he was to leave. It was at this moment that the Stormtroopers were attacked by an unseen foe and Kilos, not wanting to spend any time in an Imperial prison cell, decided to leave their visual range.
