Nullstones are a type of magical item created by the ancient Irda. They are unique in that they absorb nearby magical energy. The Irda designed them to help protect their important buildings. Some nullstones were very powerful and were as big as a palace, but most were small and placed into buildings. The smaller ones were described as a small circlet made of strands of silver, gold, and copper braided together. The ends of the strands were held together by a bead of copper. The bead would have complex engravings on it. The center of the circlet had a piece of dull black glass set in it.
The power of a nullstone is not in the metal but in the shape of the object. If a nullstone is smashed or melted it will loose its power. The art of making a nullstone was lost with the High Ogre civilization. The Silvanesti Elf Waramanthus tried his entire life to make one but failed.
Most nullstones were destroyed by the time the Human Empire of Ergoth rose in power. There were two of important note in history. One was possessed by Gomian a priest in the city of Ulladu. Pakin Zan sacked the city in order to acquire it. Years later when Pakin Zan was dying, a large black rook flew in and snatched the nullstone. Pakin’s nullstone was never seen again. The other nullstone of note was owned by Tol. Tol found the nullstone by chance at the Great Confluence near the Cear River. Two years later he learned of the true properties of the artifact. He carried the nullstone for decades until he finally buried it with his mentor Egrin Raemel in Zivilyn's Carpet.
