Battle of the Harvest

The Battle of the Harvest was the first attempt of the Master to break free from his entrapment at the Sunnydale hellmouth.

Background
After moving into the New World in 1937, the Master settled around the location that would later be known as Sunnydale. An earthquake trapped the Master underground for 60 years, until the opportunity for the ritual called the Harvest could take place and free the ancient vampire from his entrapment.
