Spelrite, known as Stormstones to the Dwarves, is a by-product that is found in the wake of Mana Storms. In its unrefined form it appears to be a slightly blue colored volcanic stone. unrefined it is very powerful but also volatile and often breaks down after about a day. Once refined it comes in a powder form that is less powerful but lasts indefinitely. It is extremely valuable as it is the only known substance that allows the use of magic. Human priests and wizards use it as a reagent to their spells and Dwarves use it in the creation of runes.
