To make matters worse, Mantle disables the defenses for the entire Alliance, putting the fleet in jeopardy. Meanwhile, Jewelia and Graveheart launch an assault on Sternum's camp but are repelled due to its advanced weaponry. Once the rightful ruler of Bone, Sternum seeks vengeance against Femur after being usurped. As Graveheart and Jewelia withdraw, Tekla reluctantly hands over leadership to Mantle, who unveils a crucial defense key originally given to Jade.
