MageGlass

MageGlass
Considered the true mystery of the Valley, this substance is clearly the building materials of the Olden Times - Anything advanced that has been unearthed seems to have some sort of MageGlass element to them. The best theory so far is that it is a manufactured material of unknown origin that can somehow store and continually produce magical effects using some unknown power source. So the while any arcane practitioner can, for instance, cast light and maintain it through his own power, by casting it into MageGlass the spell continues in perpetuity.

Alas to this day the Mejjitic order has yet to work out how to manufacture the glass, nor the process by which to cast arcane power into it.
