The Aurora Stone emitted sparks as Thirteen carefully inscribed runes, line by line, on its surface.
His blink slowed, eyes intently locked on the stone. Understanding he was focused and in the flow, his lovers made no sound to avoid disrupting him.
Although curious about where the rainbow-colored stone had come from, they decided to wait until Zion finished whatever he was doing with it.
"Sherry, please drop your blood on this stone," Thirteen said after a few minutes had passed.
"Okay." Sherry didn't hesitate to prick her finger and press it, letting her blood drip.
As soon as the crimson melded with the stone's surface, the color of the Aurora Stone changed into orange. This lasted for a few seconds before returning to its original rainbow color.
Thirteen then continued carving more runes. After a while, he turned to Erica and also asked for a drop of her blood.
