If you ever get stuck on wanting your world to make geographical sense, then may I present the world map of the most popular D&D campaign setting, Toril AKA The Forgotten Realms/Faerûn

Why is Zakhara a square? Why is The Enlightened Arm shaped like that? What happened to Laerakond? Why does the north have no topography? Why is the compass tilted?

Point is, if the most popular D&D setting can look like this, your world can also look like whatever you want. Go ham!
