Another light appeared in Carnathia's hand after she uttered the verses. But unlike what appeared in Gray Flame's hand, in Carnathia's the flame engulfed her entire palm. It was warm for a moment before the blaze stung her with a fiery heat. 

"Steady," murmured the masked elf as she squeezed her left hand. The fire was warm again like there was a translucent barrier insulating her palm from the burning flame. However, true to his warning earlier, the mysterious power quickly drained her and the longer the fire remained, the more she felt like she was steaming from the inside.  

"You are trying to invoke the power of those you never knew before," warned Gray Flame. "And without my barrier, that might hurt you. But my power can only bargain, not to repel this grace. So while the grace still tolerates you, you must pick those you deem worthy and give them the light. That would help them defeat the phantoms." 

After saying that, the fire on Carnathia's hand swirled and concentrated on her palm before refining itself into a radiant glow. Gray Flame released his grip on her other hand and exclaimed.

"Go! Before you burn yourself!"
