Abigail smiled and shook her head at him--she truly didn't know.
"Enough," she said after a moment. "I feel like...me. The most distilled version of me, perhaps. But I think..."
She shuddered again, and when her form flickered, it took longer to come back into focus. "I'm so sorry, my loves," she whispered, cupping Zephyr's cheek in one hand and Asta's in the other. "I don't think I can...hold this form for long...I..."
She closed her eyes as though concentrating, then breathed, "I am with you. I am always with you..."
She faded, her form dissipating into the greenish glow that had surrounded her body. Except...
Except her body was no longer there. For just a moment, where Zephyr had been cradling her form, there was an outline of green light. Then it was shrinking, faster and faster, until it solidified into a stone of bright green jade, about half the size of a human palm.
The stone seemed to tremble, then it leaped, fastening itself to Zephyr's chest, right in the center of his breastbone, as whatever scrap of power Abigail had absorbed, whatever piece of his essence his love for her had instilled and allowed her to carry their child, locked itself back into place in his physical form.
