Age of magic year 238 the group called the true humanity attacked each of the human kingdoms in a sudden night raid. Even though the attack was so sudden that each human kingdom was caught by surprise they still had something prepared just in case. They already knew of the threat the true humanity possessed and they had their armies ready in case of emergencies. But nobody had guessed that there would be many traitors in their ranks.
The true humanity were able to reach deep into their ranks. The Northern Kingdom had their prince turn traitor. The Eastern Kingdom had two of its immortal level warriors join the true humanity. As for the Western Kingdom, most of the head engineers turn out to be from the true humanity. The magic cannons that they were trying to perfect had been stolen and used against them.
