>"I'm not entirely sure," says Ran. "My primary knowledge of them comes from Yukari, and some reading that I've done. As far as I know, they're old artifacts, old even for youkai. I suspect they may have been made in a time when Yukari was quite young, from someplace outside Gensokyo. I'm not sure how they came to be here, I suppose the same way anything ends up here.
>"My main knowledge of them comes from Yukari's experience. Some centuries ago, six or seven of them, a human managed to find them somehow. This was back in the bad old days, and she used them to defend the human town from youkai and made enough of an impression that even Yukari took notice of her. She also used her power to take control of the town, and ruled it as a queen. I can't find many details on her reign, but it seems to have been a mixed bag. Regardless, she was quite dangerous. When she passed on, the gems were lost. It seems her heir didn't use them, or perhaps could not use them. Then were lost after that. From what I've been able to gather, her daughter took it upon herself to hide the gems away. It's been something of a passion of mine to try and find them while Yukari is sleeping and doesn't need me around."
>She sighs. "As for what they do, Yukari told me that could invoke many kinds of deadly magic, blending their powers together in curious ways to make even greater spells. Given that their original user lived to a ripe age, I imagine they may last for at least a human lifetime. I don't know if anyone else even knows they exist. Well, it seems Yuyuko had some idea. I don't think anyone else knows of them."
