Later that night, several high-level gunter wizards finished casting a series of divination spells on the castle and announced on the message boards that the shield around the castle was generated by a powerful artifact called the Orb of Osuvox, which could only be operated by a wizard who was ninety-ninth level. According to the artifact’s item description, it could create a spherical shield around itself, with a circumference of up to half a kilometer. This shield was impenetrable and indestructible and could vaporize just about anything that touched it. It could also be kept up indefinitely, as long as the wizard operating the orb remained immobile and kept both hands on the artifact.
