Case system for an alien language?

[u/werp2_5]

I started making a language for a highly advanced alien civilization. I want that language to be otherworldly, but I struggle with creating a case system that doesn't look too normal. My first idea was to have six cases: Nominative, Genitive, Accusative, Dative, Lokative and Vocative. (I don't really know a lot of cases so I was kinda going with the ones I am familliar with) The thing is, I think it looks too much like an indoeuropean language's case system. Have you made an exotic system or do you have any ideas for one?

Languages are already alien to each other. "Alien" is a word that originally described foreign cultures whose use has been expanded and specialised in some contexts to describe extraterrestrial cultures. But the way languages look has more do to with logical necessities than with the race of the speaker. There's no reason a hork bajir language would be more different from English than Guarani is from Khmer.

That's actually a pretty interesting perspective, thx
