Scars of Faerûn
Lord Ao is the Overgod of the worlds Abeir and Toril. As Overgod, all deities and primordials of Toril, even those who also operated in other spheres and planes such as Lolth, were subject to him. To be more precise, only aspects of gods directly connected with Abeir-Toril are under Ao’s power. Otherwise extra-planar deities were unaffected.
