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 like to do very literal place names. Bluelake, Understar, Northpoint, Highridge. It’s realistic, it’s pretty easy, and it avoids the problem of unpronouncable and hard to remember names. Also it instantly tells you something about that place.
I need to get in the habit of doing so for ttrpgs.
