We really are looking at ways to bring all the settings back

Does all (arcane, divine, natural, etc) magic rely on the Weave?

Do any entities hold jurisdiction over the various waters and coasts of Eberron?

Is Io, the Creator of Dragon Gods, related to the Progenitor Wyrms in some way?

Do you regret after 13yr the PHB races/classes are all Forgotten Realms…

Is there any reason why more dragonmarks couldn’t show up on monstrous droaam…
