Echo Stone

A unique ore found exclusively in the mines near Saphi Sashi, its highly out-of-place properties make it hard to retrieve, and even harder to find uses for.

Appearance
Echo Stone is a crystalline rock, resembling that of a cracked open geode. It comes in two main forms: blue Echo Stone and purple Echo Stone. Regardless of color, the two different shades share the same properties; tough but brittle, sharp but easily loses its edge. Due to this, it can't be used in the same vein as an iron or an alloy metal, and must instead be treated like that of a fragile gem. The blue and purple halves can be split apart with enough force (though not with a weak force like, say that of a child) and be laid apart without much incident.

However, what makes Echo Stone truly unique is its ability to 'attract'. If an individual holds one color and is in the vicinity of a stone of the opposite color, thinking of the stones combining together actually causes both stones to seek each other out in an attempt to rejoin. And if one of the stones is held in a grip or vice of decent strength, the other side of the stone will, instead, fly towards the stationary stone. There are several things to take note about this effect:
 * 1) If the person that's thinking of the stones combining were to lose possession of the stone for any reason, the effect immediately stops.
 * 2) If both sides are held in a vice like grip, often the half with the weaker grip will be forced towards the ore with the stronger grip, bringing the unfortunate person or object with it.
 * 3) Though it is usually safe to keep Echo Stone separated by its two halves, it is not recommended. As, due to yet unknown reasons, the stones have a tendency to attract to one another given enough time.

''I'll add more here if we learn more from Echo Stone. But even when I was living in Saphi Sashi, we knew very little about how this mysterious object worked.''

Uses
Due to its specific 'rules' and brittle nature, finding uses for Echo Stone is hard. Simply harvesting it in pieces larger than tiny shards (the size of shattered glass) is extremely tough and takes days for the smallest sample. Even then, there's not much Echo Stone does that another object wouldn't be able to do but better. Its peculiar, unpredictable nature also means that it is dangerous to have around without a purpose. And though methods have been attempted in order to melt Echo Stone with metal, porcelain or even glass, these results have barely been successful. As such, until a normalized use can be found for this odd stone, it shall ever remain a collector's item, to sit collecting dust as nothing more than a novelty children's toy on the shelves of Saphi Sashi citizens.
