Found by rotating the map upside down, going to the bottom left corner (bottom right when turned) to the very edge and then zooming in on maximum to see the outerworld mesh (its huge btw - https://www.reddit.com/r/mountandblade/comments/ftm7o3/whole_map_found_in_bannerlord_game_files - if you wish to see it).
Conversely, the kraken can be spotted over a group of islands which resemble those of the iron islands from a Song of Ice and Fire. Coincidence? I Greyjoy you not.
