Preparations
Beings from Noah's homeworld and the Beast World were rapidly moving around as preparations were underway for them to do something grandiose.
The Rulers of the Demon World were heavily weakened at this moment in time with more than half of all their forces meeting True Death in the Lost World of Atlantis. There was fear and uncertainty in all of their hearts, and Noah chose this time to strike and take out those involved in causing the deaths of many beings across the two worlds.
He did not want to consider himself a senseless killer, but there had to be reckoning for those who caused senseless harm to many weaker beings based on their own motives.
