The Valkyrie and her mirror image square off, tense seconds ticking by as they look for an opening. The Adversary asks if she still seeks Mastery. As Valkyrie affirms that she is, the dark warrior springs forward. Valkyrie however is ready and steps to the side, turning the attack into a glancing if still painful blow. Before the Adversary can regain her footing, Valkyrie brings her own blade down upon her, wounding her grievously. The Adversary lashes out with magic trying to crush the mage’s windpipe. But Valkyrie’s defensive spells weakens the attack to harmless levels. She returns the attempt with a fierce cry putting the Adversary off balance. As the black silhouette throws a bolt of lightning past Valkyrie, the mage steps forward and slices through her with an overhead swing. As the Adversary dissipates, she concedes and Valkyrie achieves Mastery of Forces.
They return to the temple quickly and find that the Tyrant’s army is on its way. Valkyrie decides to split the group into two teams. Colt and Adele will ride with the cavalry to deal with the Crusticon while Mammon and Valkyrie will kill the Tyrant and destroy the Emerald Star.
In preparation, Colt boosts Adele’s strength. They plan to use ropes and Adele’s Death magic to trip the war machine. This will give Adele the chance to climb up onto the robot and attach the device they received from the Old One. Meanwhile Mammon ensures Valkyrie’s mind is well defended and cloaks them in mental illusions so that the army will believe them to be fellow soldiers. He then creates a portal so both of them appear behind the army, with the plan being to infiltrate the army and sneak up on Tyrant.
Once they portal in, they find it easy to blend in due to Mammon’s magics. As they approach the main carriage of the Tyrant, they can hear the sounds of battle in the distance as the first of the riders engage with the enemy troops. Mammon forces his way into the carriage as Valkyrie encloses it in a wall of force to keep the other troops out.
Meanwhile on the other side of the battlefield, Colt and Adele charge the Crusticon, as the soldiers atop it shoot their beam weapons at them. Many their troops die before reaching the war machine but Colt is able to control their giant lizard and get within range. Adele destroys the ground where the device next steps and it falters. She leaps off the mount and begins to climb the towering war machine. At the same time the allied troops lasso ropes around its other legs trying to pull it down but to no avail. Adele completes her climb as the Crusticon resumes its charge to the refugee’s defenses. She attaches the Old One’s device and jumps back onto lizard with Colt.
On the other side of the field, the Tyrant attempts to use the Emerald Star to convert Valkyrie and Mammon to his cause. Mammon’s mental shielding however protects them and Valkyrie shrugs it off with a quip about the evils of abducting children. As she attacks him, he throws a wave of fear at her which she effortlessly ignores. Between Mammon’s mental blasts and Valkyrie’s sword, they cut him down and Valkyrie grabs the gem from his fallen body. Focusing her will, she uses it free the minds of his soldiers, removing his evil influence.
As the pulse of liberating green energy sweeps over the battlefield, an earth shaking blast of white engulfs the Crusticon destroying everything within a hundred feet of it. Adele and Colt find themselves battered and on the edge of a crater. The war ends with the refugees saved and the Tyrant’s hold broken. With the struggle over, Valkyrie takes the Emerald Star into the desert and evaporates it with her magic.
