Your master, the infamous separatist general, General Grievous, stood before the battle droids, instructing them, commanding them.

General Grievous: "It won't be long untill the army of the republic track us here, I am commanding you to stay wary and prepared at all times."

You stood next to him, listening to his words although they were not intended for you. Once General Grievous was finished and dismissed the battle droids, he turned to you.

General Grievous: "As for you, my young apprentice, use your lightsaber training, and eliminate the republic's army. If you see General Kenobi, report to me and don't interact with him, I will deal with that jedi slime, myself."
