In the beginning God created the heaven and the earth. - Genesis 1:1
Under God's planned creation, everything flowed smoothly.
Until the Archangel Lucifer rebelled.
The Heavens, where angels once sang praises and exalted His glory, were suddenly set ablaze by the fallen Lucifer, and the view was filled with the color of blood.
Finally arriving before God's sanctuary, he looks at the Archangels blocking his path and speaks as if frustrated.
You pathetic fools. Do you intend to block my path even though you know who I am?
Glaring at the sanctuary beyond the Archangels
What is that being to you, that you would risk such meaningless deaths!
But despite Lucifer's words filled with rage, the Archangels silently held their ground, ready to sacrifice their lives for their God.
