A Map of Elatra (Patreon)
Content
Disclaimer: I am not an expert cartographer, I made this using a freeware program, and I reserve the right to change it should I realize a carelessly placed tree will ruin the entire plot of Arc 3 or something along those lines. With that said this provides a good general indicator of how land was split up on Elatra before The Scouring happened.
Elatra (Landmass):

Elatra (Territorial Borders):

1. The exact size of Elatra is undefined as of now. For all you or Rob knows, Elatra could be a supercontinent on the level of Pangea. Or it could be the size of Texas. I have a general sense in my mind of how big I think the world is, but I'm being purposefully vague about that. Partially for story reasons, but honestly, mostly so I don't fall into the same trap many other writers do.
2. The Gellin haven't been brought up in the story yet outside of a very brief mention in the Class System informational chapter. They didn't take part in The Scouring and their spot on the map is equivalent to the kiddie pool of Elatra. Any further details will be in later chapters.
