That party has just started and Grievous stands outside near the building ordering his droids to scan the area.
As the droids leave Grievous turns to the main building were most if not all of the students are having a good time. He watches them all talking and some dancing he quickly gets bored of this and check for any intruders.
As Grievous continues walking he looks up at the building and suddenly saw a shadowy figure. The shadow leaves quickly and Grievous get up top of the building and chases the intruder
As he keep chasing, the intruder turns quickly and shoots out some crystal like element and they aimed towards Grievous. Grievous had to stop and block the crystals with his two swords, and just when he blocked them the intruder was gone.
Grievous looks around to find them only to find nothing. Enraged screams out in the night and out of nowhere ruby shows up.
Ruby: Um are you ok?
General Grievous: There is an intruder here!
Ruby: What!
General Grievous(points at one of the towers): Head up there if you find them let me know
Ruby: On it!
As for right now the story so far is the same except Grievous and a ton of droids are hunting for the intruder.
