As for the names I have a whole (overly complicated system). Basically each language in my world is a mix between multiple real world dead languages. I use chatgpt or open assistant (ik that using ai in worldbuilding is controversial but all the names are still mine) to generate words in the dead languages then smash them together. Sometimes i’ll have a word or phrase that I have it translate and then combine and shrink until it’s one word. To me, this is easier than conlanging but still original and fun.
I usually take a language or languages I want to use as a theme, translate words and then remove letters or move things around until they sound neat enough.
They get so jumbled, I don’t even know what words they came from anymore. For my most recent setting I came up with two kingdom names as Adeya and Coridia. Original they had big long Icelandic names describing where they were, and then I cut out letters, introduced new words, cut it down and so on until it became completely unrecognizable.
