Decided to make a single post because each of these 2 mods is pretty small and basically have the same goal.
The first, for the Night's watch, simply changes the localization of the Kingdom and Empire tiers of the NW title so that it actually says "The Night's Watch" instead of "The Wall". It shows up on the character screen and the map. Compatible with everything.

The second submod is for the Iron Islands. I didn't like how, when zoomed out on the map, names couldn't span the archipelago and instead were localized over each island. This submod makes all map names go across the islands, which I find more pleasing to look at. Unfortunately, I did have to add 2 straight crossings to do it, so if you don't like that, don't go for this. I don't mind because the CK2 version had even more connections between islands. This submod is also incompatible with any others that change the map (if there are any).
