Armageddon

First Elder secretly built a collection of world's most destructive weapon ever: Armageddon (아마게돈)

Each Armageddon is a powerful assault satellite (공격 위성이) orbiting around the Earth capable of creating unrivaled destruction. The satellites are capable of charging themselves by absorbing energy from Earth's orbit which makes them capable of launching one laser attack after another.

First Elder was wary of Maduke and other Union Elders which is why he built the satellites in secret.  He was aware that if Armageddon's existence was known to the other races then they would come after him and the humans.

First Elder used one of the attack satellite to wreck havoc on werewolves land. This satellite was ultimately destroyed by Rai in order to prevent werewolves from extinction.

Later on, it was revealed that First Elder has built more than one attack satellites.

After Crombell took over Union,  he started showing great interest in the attack satellites since they were capable of fulfilling his goal: wiping out entire human race.

Crombell was able to get his hands on two satellites while his subordinates continue to find other satellites. He first did a trial run on an ocean floor and the resulting destruction impressed him.  Moment later, he aimed at Rai's home which forced Rai to block the laser attack in order to save the children and countless other humans in the city.  This satellite was destroyed by Rai as well.

Fearing Crombell would activate the remaining satellites and harm the humans,  Rai started a hunt for destroying the remaining satellites.

 Muzaka help him in the process and together they destroy the threat of attack satellites.
