Grand Flame Manipulation

I create a demigod character who will have a phoenix as a soul-bounded entity. His name is Askold and he will become a transcendent absolutely invulnerable demigod once. His phoenix will be able to resurrect from ashes and generate grand flame that causes mass resurrection or Semi-Immortality.

I ask how to name this phoenix? What kind of ideas do you have? Feel free to combine different morphemes like pyro- or anything else related to it.
