Infuscoartus : Jegardiel The Demisemonger

Once Jegardiel was a proud and mighty angel, born to enlighten and protect all life from evil.
Jegardiel passes down the great knowledge and his teachings to humans so they may use it to have an awesome future so that there will be no destruction and desolation, but from time to time human began to misuse these knowledge and forsake his teachings.
through time Jegardiel fell into sadness and disappointment, then there came the twisted lord of limbs to persuade him to join his legion so that he may cull down those who forsakes him. Driven with rage and disappointment he agreed to join his legion.
And so Jegardiel sealed away his former self in his pauldron and embrace his new identity. Emerging from the flaming pool of the infuscoartus and he was incarnated as THE DEMISEMONGER.
