The Aurora, Cryos' flagship, travels to planet Rock to convince Lord Mantle to join the Alliance. Sadly, the army arrests Graveheart and the Rock King expels the Ice King determining he is still his greatest enemy. Lord Mantle condemns Graveheart to imprisonment. Meanwhile, Blokk the supreme warlord of the Beast launches an invasion on planet Rock with Voyd permission. Jade, a rock commander and a long time friend of Graveheart, releases him and they run to the Core central to activate the planet's defense – the Battle Moons. They succeed but Lord Mantle banishes the “miner” still not believing in the alliance. Despite all odds, Jade agrees to join them, claiming to need to watch her friend's back.

The Beast Planet demonstrates its might, launching an armada to attack Fire while training its powerful cannons on the Battle Moons. A stray blast threatens to destroy Ice, but Tekla and Lady Zera discover world engines hidden within the planet, which move it out of the path of the blast.
