"Look at these crystals."
Upon seeing Heidi, Gawain threw a piece of light purple crystal into her hands.
The lady looked curiously at what was in her hand, and she immediately gave a look of surprise.
"This is what you told me about earlier, the treasure house in the mountain…"
"Yes, this was taken from there." Gawain nodded. Although he did not bring Heidi along this time, he had told her about the treasure house in the Dark Range when they were in Tanzan Town. "These crystals are technology from the Gondor period. See if you can understand the rune structure."
