I hope youre not pitching this as a replacement to a full on setting book… Many people don't know what's in the books they already own. Delving into that material is a great starting point.

Don’t forget Sigil. I could never forget Sigil, which gets its own section in the "Creating a Multiverse" section of the DMG.

Curious if Sigil is a thing in the current edition of D&D? Check out the section called "Sigil, City of Doors" in the "Dungeon Master's Guide" (p. 68). The Lady of Pain will be pleased if you read it. #DnD https://t.co/cLqA2xAJpu
