Fallen Army

"An army of demons...an enormous army...stretching as far as the eye can see, like an ocean...an ocean of eyes staring at you with the intent to destroy you and everything you love."

- The Fallen Army described by a soldier The Fallen Army (落ちました軍, Ochimashita Gun), also known simply as "Helel's Army" (ヘリールの軍, Herīru no Gun) or "Ocean of Evil" (海原の悪, Unabara no Aku), is an ancient and enormous army of over 700 demons, hailed as the most powerful of its time. It was considered a major force of the demon kind during the Dragon Civil War, having contributed to many deaths onto the human armies, rumoured to have also succeeded in the annhilation of a number of dragons as well.

It vanished after being supposedly defeated during the war by the forces of both humans and dragons, but still exists, simply inactive. It was formerly lead by Helel, before his son inherited the title of leader after surpassing his father, making Balor the current leader of the Fallen Army.
