Governors earn Personal Points through completing Missions. Once enough Personal Points are accumulated, Governor Chests become available. If the Governor belongs to an Alliance, opening a Governor Chest will also grant additional Alliance Preparation Points. Point contributions are retained after leaving an Alliance. Upon reaching the required Alliance Preparation Points, the Alliance will receive exclusive bonuses for the Flamedragon Battlefield.
