Aza's fire elemental was a long time coming, an element he studied for a long time in order to fully understand and grasp it. ever since understanding what the altar in the middle of his temple ruins was, a place meant to hold an eternal flame, Aza vowed to relight it one day. with this promise came a deeper promise to understand why; why an eternal flame would be this central to a temple and a faith, why it was meant to never go out, and what it may symbolize and mean.
though Aza doesn't claim he knows the true answers to these questions, he has done his very best to answer them to his own satisfaction. he's understood fire as a life-bringer even in a vast and hot desert like his own, has seen the beauty of a flame that dances and flickers but also the destruction in an uncontrolled fire's wake, and thinks of fire now as a duality between comfort and light and caution and respect. no matter what the flame meant in the temple before, in Aza's temple now, it means reflection and growth. any guest to his temple is more than welcome to meditate on this with him, or to just enjoy the warmth in the cold nights or to watch it dance.
the fire in the temple is always ablaze, as is the fire Aza carries inside his body. his body is hollow and so the warm light shows through the keyhole in his forehead, the hole in his chest, and the fragmentation in his legs. there are embers caught in his mane and tail, and floating gently around his form. the fire is soft and warm, and almost always carefully contained within his body.
