The Aspid presented Arin with a riddle:
Arin thanked the Pierced Aspid and hastened back to her sister, the crystal clutched in her hand. Her sister's condition improved dramatically, and soon she was on her feet, smiling once more.
"What can be broken, but never held? What can be given, but never sold?"
"Take this crystal to your sister," the Aspid instructed. "It will heal her, but remember, a promise is a powerful thing. Use it wisely."
