@TheEdVerse I hope you are well! A silly play cosmology question, has Elminster advised on the planar status of our universe? Is Earth part of the Prime Material Plane with Toril? Is it separate from the multiverse? Does it sit in a different Prime? 🙂

Earth and Toril exist on different Prime Material Planes, in a multiverse in which there are yet other Prime Materials. Those who know the right magic, or find the right gates, can travel between Earth and Toril.
That’s where the name of the setting came from, … 2)
…back in 1967. The reason we have legends of dragons, griffons, etc. on Earth is that the gates were formerly well-known and widely used, but we've now "forgotten" how to get to the Realms.#Realmslore
