He walks with daylight at his back
His feet leaving a trail of ash
Spitting embers with each breath
Bestowing warmth and life
Sowing destruction and death
With arms enflamed he brings fire
He comes to pass judgement upon the world
I adore fire. It's so beautiful and so dangerous, life and death in a nice little fiery package.
Fire also acts as a passage to the spirit world or the realm of the gods. Across all faiths prayers are offered before a flame of some manner, that flame carries our prayers to the other world where the spirits and the gods hear us. Fire is also a pure element, it burns away corruption unlike it's brethren who can be tainted and sullied but are no less important.
