Golden Orb of Siluvanede

During the heady days of Siluvanede, sun elves from the greater noble houses crafted arcane orbs that offered protection against an enemy's initial magical assault. These items, called golden orbs of Siluvanede, could be carried by their owners or suspended from delicate chains and worn like pendants; Some were even enspelled to float around their owners in a manner similar to that of ioun stones.
Each orb is a 1-inch-diameter sphere of purest gold imprinted with the house symbol of a noble Siluvanedenn family. These orbs were so expensive to make that each noble house possessed only one, which was traditionally carried by its eldest member.
A golden orb of Siluvanede contains a Siluvanedenn abjuration spell very similar to Elminster's effulgent epuration. The protection offered is continuous, although the orb can absorb and negate only one spell or spell-like ability that targets its owner each day. The wearer can choose whether or not to let the orb absorb a particular effect, although he gains no special knowledge or insight that allows him to identify an incoming spell before making this decision.
When Eaerlann and Sharrven conquered Siluvanede most of the golden orbs were confiscated and placed within secure vaults. Many of the newly released Siluvanedenn fey'ri now seek to reclaim their stolen ancestral treasures.
