It’s apparently procedurally generated and infinite, and gets more dangerous the farther out you go, but theoretically can 8 strong players go out in every direction and load a large amount of terrain?
Would the unloaded sea be regenerated if you come back the other way
I’m willing to bet it will work similarly to the Haine desert from Pokémon sun and moon(search it up) where it’s a lot of different chunks and if you go from one chunk to another and then back it would be different than the original chunk you were in. Some islands in the dark sea will be randomly generated while most will be premade and randomly distributed.
I imagine navigating the Dark Sea will be tantamount to sailing in Deepwoken at night during a snowstorm (you can only see like 20 studs in front of you).
