Arnold wasn't the only one feeling the effects of the Angel's presence. The ones who had previously given up on fighting had once again taken up the arms to fight till their death. They felt invincible. Their foe was a godly monster, but so what? They won't allow a mere monster to trample over them. At that moment they felt like gods... They were gods.
Even Tiamut was concerned about the appearance of a new foe. Yet it wasn't her first and only time seeing the Angel until now. The memory of the angels she had wasn't a pleasant one, to say the least. Why do you ask?
Because on a fateful day, she was cursed to live her life in her form of a dragon. And the one who cursed her was none other than the Immortal One, Shiva.
