Demons (ShatteredRose23)

Demons, unlike devils are various different races of supernatural creatures. Demons can either look human or can look like monsters. The Demons were created by Lilith (The Mother of Monsters) after she left God and became one with Lucifer. She Created three different demons (known as the Demon Kings or Gods of Demons) who then created the various types of demons and started the Demon race.

Due to their strength and unique powers the demons started working for the three main factions as soldiers causing multiple civil wars between the demons.

Summary/History
Demons (true monsters) lived peacefully in the Demon World until Angels, Fallen Angels, and Devils started recruiting different races of demons as soldiers. After the Demon Kings died the different races of demons were thrown into chaos and started making pacts with the three main factions which in turned sparked multiple civil wars that almost wiped the Demon Race out.

Fearing extinction, the seven strongest demons got together and created the Council of demons and broke off allegiance with the three main factions. At the end of the Great War, the demons were given large sum of land in the Underworld as retribution and the fallen angels and angels promised to never bring the demons into wars again.

Council of Demons
The Council of demons, made up of the seven strongest and oldest demons, who power even surpass that of the original Demon Gods. The council usually tries to stay out of conflict/neutral in the affairs of the three main factions but will give support to cease war when they can.
