For Susan's condition had been far more severe than anyone could have imagined. Her internal injuries were so terrible ... Alice Longbottom was seriously concerned that they might lose her altogether. Enola's mother, Arianwen, had been called in to help stabilise her. Arianwen had unique gifts, not just with ancient runic magic - in which she mentored Harry - but also with crystal-based magic. It had taken a few false tries, but they'd eventually found a configuration of healing stones that worked. Susan was now held within a field of vibrational frequencies from the crystals that were keeping her alive.
