Healer

In the end, Aion makes the enemy have a mental breakdown after he takes his sword and begins to cut his legs covered in ice. He thought that the guy was the head of the enemies, but that wasn't the case. He spilled the beans all too easily before Aion claimed his head. If that wasn't suspicious, he didn't know what it was.

Despite that, he had his clues that the one leading the whole group indirectly while receiving more help from the future was a woman that was controlling the Eastern side of the county. While her territory didn't expand that much, she was the one who forged the special materials that they had and gave them to the others.

"This guy didn't have anyone whom he could trust with such a powerful sword, so he kept it," Aion thought. "This isn't material I have ever heard of… so maybe his suspicions aren't unfounded."
