@jonikorpi my approach to this would be to first flesh out the game world, in a fiction-writer's worldbuilding way, and *then* approach this question again
That is not in any way meant to depreciate what you've done so far, the visuals are lovely, but the name IMHO kinda needs to tie things together in a concise, memorable and introductory package and there don't seem to be enough things to tie together yet (based on what I see in the thread), any name at this stage is probably gonna be very hollow
And if you go the other way, start with a name and design other elements downstream from that, that'll probably yield results that are LLM-grade mediocre, probably not what you want at all 
Like, maybe you'll find elements bright enough to make into the name. A fancy mineral or gem, a historical/legendary (or both) figure, a fabled location, a species causing a ruckus across the world
Maybe gameplay-defining elements
What I'm saying is it might still be too early for this
