So my partner and I were wondering if there was any information we could get about the mysterious deity that Lord Ao refers to as “master? We’re also kind of just being major fans right now and wanted to know if you still play D&D? Yes, I still play D&D!
As for the mysterious "master," that being is a mystery to me, too; it was a TSR addition to the Realms, just like Ao. The most popular theory is that Ao reports to you, the Dungeon Master, so you the DM are the "master." But that's speculation.#Realmslore— Ed Greenwood (@TheEdVerse) October 18, 2019
