Repeating my tweet from last week in hopes for an answer! “Hey Ed! Is there a true cannon of Asmodeus’ origin story? Or all we know are myths and legends still?” Hmm. Didn't get this one the first time around.
Many have written of Asmodeus's origin in quite a few official D&D products down the years. Many of these lore sources conflict…which tells you we're all mortals writing the best "truth" we can comb out of legend.#Realmslore
