Indestructible

A towering bonfire of pristine flames enveloped both Nephis and the vessel of the Gate Guardian, rising high into the sky. It bloomed like a beautiful white flower, suffused with both brilliant radiance and incinerating heat.

The soul flame burned so hot that, for a moment, Sunny actually felt dreadfully cold, as if he had been transported back to the frigid fields of the Antarctic Center. 

With a curse, he staggered back, fell, and rolled away. 

'Hell!'

Neph's flames could be warm and nurturing, healing and purifying anything they touched. But they could be ruthless and ferocious, destroying everything in their path.
