Third person POV
That Lightheart was furious that Sol destroyed his crystal golem, shouting at the Spiritheart, "How dare you!"
Glaring at him, Sol responded with, "That's what you get for being so selfish and for joining the Old Faction."
As his fellow Lighthearts attack the palace guards and troops, that Lightheart snapped and drew out his weapon, a massive scythe, and charged towards Sol, swinging it around in fury.
But then, Sol dodged it quickly with reflex, switched to his heavy, crystalline battle axe, the same he used when he was at Vanworth, and hit the ground with it, summoning crystals to trap the Lightheart.
Now being imprisoned by Sol, the Lightheart, whose left arm was severely struck by the crystals, tried to call for help to his fellow Lighthearts, but Sol was one step ahead of him and the others because his academy students had killed and slaughtered most of the Old Faction members, except for the two controlled legionnaires.
As the Lightheart hurled insults and curses on him, Sol used telepathy on one of the fighting soldiers of one of the two, controlled legionnaires, only to find out that a controlling spell was casted to him and his fellow soldiers by a Lightheart member, another one of the seven perhaps.
Then, the 7 Lighthearts noticed that their friend, which is actually their high-ranking captain of their squad, was trapped in that crystal prison, and abandoned their fighting to use their light magic to free their captain. They did, but it comes with a cost: their Lightheart squad captain lost his left arm.
In pain, that Lightheart captain of theirs looked up at Sol, who was holding his crystalline battle axe, and shouted angrily, "You bastard!"
"That's for being so self-centered," Sol told him off, "just like the other Lighthearts. Now, get lost."
Eventually, that Lightheart captain collapsed to the ground in severe pain, giving up.
Wanting revenge for their injured captain, the 7 Lighthearts are about to retaliate and attack Sol when their captain stopped them, saying, "Don't! It's not worth it. Let's report this to our queen."
And so, his fellow Lighthearts just gave up and showed their wings. The Lightheart captain then managed to get up and showed his wings, before he and the other Lighthearts flapped their wings and flew off towards the sky back to their mountainous kingdom to report all of these to their queen, abandoning their part in the coup.
Watching them from the distance, Sol thought, "I knew she would do this."
