- "I'll meet you at our secret base in Sector Four."
- ―Grievous, to the crew of the Malevolence
Sector Four was an area of space occupied by the Confederacy of Independent Systems around 22 BBY during the Clone Wars. During the war, the Confederacy built a secret base there. The Confederate General Grievous planned to retreat and meet his warship, the Malevolence, at the base, but the warship was destroyed before it could reach the base.
