A Key Event

The most important event was the Death of Citriel.

Finamo loosing his youngest brother was what made him so hateful. It had driven Finamo and Idariel to try and murder Lucifer out of hate and vengeance.

They had gotten kicked out of heaven for their hatred and wrath. While they fell down to earth they lost each-other, but Idariel blames Finamo for the death of Citriel

and spends four years tracking him down. Just so that he can beat Finamo for not saving him but they both have to come to terms and accept the fact nothing can change the past.
