From the bones

She seemed too startled and distracted by whatever had caused her to back up into him to begin with to answer his question, but when she looked down at the crystals on the metal he was carrying and then turned her attention back to a rib bone that had been laying on the ground beside her he started to put the pieces of the puzzle together himself. He watched as she very carefully picked up the bone and put it next to the bar of metal, comparing the two crystals. They were indeed the same, though perhaps slightly different shades of blue and purple. The one he was carrying was much larger and had clearly been forming for a longer period of time while the one that had seemingly startled her was much smaller, but he assumed still growing.

"No idea," he said with another shake of his head when she questioned the crystal's existence, eyeing them curiously. "I found these in the barracks while I was collecting pieces of metal for my smithing. I've seen plenty of crystals and gemstones of all kinds, but nothing that forms quite like this and certainly nothing that glows like this does." He lifted a paw to tap the crystal with one of his claws, watching the glow react to his touch, pulsing more brightly as he tapped it. "I wanted to try breaking some off to see if I could use it in a piece of jewelry, but... now I don't know if I should." He hadn't realized how much these were popping up on things and the fact that they could grow was a bit disconcerting.
