Herrscher of the Void's Army

"I'll kill everyone of those hypocritical adults. However, I can let you go, you look to be the same age as me. Also, there is the scent of Honkai on you. Do you want to join me? How about it? This way. I'll let you live to witness the destruction of this world."

- Sirin attempting to bring Theresa to her army.

Herrscher of the Void's Army or Armageddon Forces was a Herrscher and Houkai order that followed the 2nd Herrscher, Sirin in the early 21st century and were responsible for the initiation of the 2nd Houkai War. They are the main antagonistic faction of 2nd Lawman prequel comic book and a posthumous organization in Honkai Impact 3rd mobile game.

They were fanatics dedicated to Sirin's ideology of genocide and they sought to destroy human civilization and provoke a war with the Houkai and human race, overturning the Shicksal's organization and eventually exterminating humankind by starting the Third Apocalypse upon the world with release of billions of Houkai creatures upon the planet. While many of its members were Pseudo-Herrschers whom wre also victims of Shicksal's Babylon Tower, most were simply Houkai creatures that followed Sirin thanks to her immense power and hatred for mankind.
