As part of their ritual in the Ziggurat beneath Whitestone, the Briarwoods created a marble-sized spinning sphere with magic-negation or -absorption properties. Later, Vex'ahlia asked Shaun Gilmore what it could be, which reminded him of a Sphere of Annihilation. Such spheres were typically larger than the marble-sized sphere described by Vex'ahlia, but Vex suspected that this one would have grown in size if the ritual had continued.
