 Chrysler starts with us gathering the Council of Light to reforge the Chrysler spiral key. The burrowers are trying to overthrow the Umbra Queen. We learn that the Umbra Queen is going to destroy the burrowers' strongholds of Peppergrass Nook and Queen Myrtletown. We get the comb key, which unlocks the gate to the last wood. We get into the last wood and meet their resistance. We disrupt the operations at Tyrion Gorge to push back the Umbra Queen's plan to drop Kermes fire on the burrowers. We hatch some dragonflies, we take control of the banyan tower, we light a smoke signal and the honeycomb wall gets blown up by the flying burrowers. We then storm the Eclipse Tower. We free the caretakers of the tower from Morgant's control. We learn about shadow magic, a dangerous variation of moon magic. After our success in the tower, we restore bastion to what it was before the war. We make peace between mice, sugar gliders and bees, and focus all their forces on stopping Morgant. We force our way to Ghostog, Morgant's first warlord, and defeat him and recover the dying starstone.
