Sapphire (Uisce)

This blue crystalline structure shimmers and glows, the lights flickering through it as if the crash and flow of waves. It is cool to the touch, but its temperature fluctuates, as if the water under the sun.

Properties

Material Characteristics

This flawless blue stone, seems to flicker with the ebb and flow of the water, as if the tides or flow of rivers. It is cool to the touch as if a river breeze. To those without magickal training or knowledge of the art of runesmithing, that is all they see, all they sense.

Physical & Chemical Properties

As with the others, these stones house pure manna, energy of Uisce, untainted by Tzeentch's curse, by the Void. As with the others, they are rechargeable, though should a magi try to cast through this filter, drawing their own energy and pulling the corrupt manna through themselves and into the stone, using themselves as the conduit....it arguably could be done. But catastrophe likely awaits.

Compounds

Dwarven and Gnomish craftsmen however, have found another less dangerous and in their opinion, more efficient use of such crystals. Through a careful and well guarded secret process they can grind such stones into a fine powder. This powder remains charged with Uisce energy. When rune-crafting, through a painstaking ritual that can take days, they can imbue the runes they etch, filling the etchings with this powder, and through this rune-crafting, and indeed, magick like ritual, they can imbue an item with the blessings of the element. This art has always been rare and practiced with the utmost caution, as it is exceedingly taxing, pushing the craftsman to, and perhaps past, the absolute limits. More than one relic of a bygone age has its story of origin in legend involve the death of the smithy whom made it, trading life for perfection of craft. Such an idea is not just mythical fancy, and because of this, only true masters of the forge may take students and train them in this art, and even then, they may only take one in their entire lifetime.
