Lavok's Sphere, also known as the Planar Sphere and referred to almost exclusively by that moniker, is a massive and wondrous piece of arcane engineering that appears in Baldur's Gate II: Shadows of Amn. Created centuries ago by the wizard Lavok, for whatever reason, the Planar Sphere has recently reappeared in Faerûn, manifesting in the Slums District of Athkatla. The Cowled Wizards have been unable to breach its exterior, but divination have revealed that the blood of a descendant of Lavok would open the Sphere and allow access.
