Cassiopea reveals that Emre is alive and warns that the war cannot be won until Devas is reclaimed from the enemy. As the united armies of the Diwatas, Hathors, and Sapyrians march toward Etheria, Avria strikes first using the Air Gem, nearly suffocating them — until the Earth and Water Gems turn the tide. Despite Cassiopea's plea to delay the war, Pirena, fueled by vengeance for Mira, forges ahead with Ybrahim, determined to bring down Asval and Etheria once and for all.
