@TheEdVerse I was looking over a copy of the old Principalities of Glantri gazateer earlier this year, and a peculiar idea sort of took up residence in the corners of my mind. Without putting it all out there, is there any chance that there was ever an intention or an idea of connecting Mystara and the Forgotten Realms in any sense through the Principalities? It's about the magic users

Like the World Serpent Inn? Have one of the back rooms open up onto Mystara? Sure it isn't strictly mentioned that there's a portal there, but I've used it before as a connection. Between Mystara and Sigil and Mystara and Toril. 🤷‍♂️
