After the Animorphs are returned to their own time and narrowly escape a battle at the Yeerk Pool with their lives, Rachel awakes from a dream early in the morning with a sudden realization - the Kandrona source was located at the top of the EGS tower, and the Ellimist had shown them the alternate future so they could have the chance to change the future in their own time, by destroying it. Rachel wakes the others, then after discussing the situation in Cassie's Barn, they head out to the tower at about 5:10 in the morning, and begin to morph battle morphs. Marco, in gorilla morph, punches through the door, and the Animorphs head inside and go toward the freight elevator, which can carry them in their morphs. Jake, Rachel, and Marco go first, leaving Cassie and Ax to keep track of activity
