The being that attacked Boreas resembled an octopus, but instead of tentacles, it had arms. The hand had eyes in their palms that accurately resembled the demonic entity that Rowan had seen Tenma summon on the battlefield, it even had the aura of a Demon.
Although Boreas had called Rowan by his name, Rowan was not fooled, he had not revealed anything of himself to the god, and he would be foolish to reveal himself even if Boreas was correct.
He expected that Boreas would begin to fish for information next, which was good. While he would be busy trying to crack Rowan's disguise, he would be doing something else.
Rowan had already covered the entire vault using his Aether, creating a shield of unnatural black ice that was resisting the influence of Destruction and blocking Boreas from escaping this place for a short time.
