Add a large island or a small continent that has lots of stuff on it including, a structure that has a phasegate either built by the architects or the Axum where the architects and Axum would talk and do stuff. maybe add that they had an alliance. also add some suit or tech that would allow the axum to go on land and also let us use it for any possible pets in the future. also if you want it could be a stargate as i have found many things that hint that both the stargate universe and the subnautica/natural selection universe are both the same universe. (please don’t change this as i like the idea its fun and also allows for more expansion for both stargate and subnautica.) ofc ik you won’t say if i’m right or wrong but it would be cool as well ik the human phasagates are most likely blue and the stargates are blue and earch seems to like blue circles and the stargate is a cicrle. i am going off track now but some structure on this landmass and a few unique biomes and a structure would be cool maybe a few architect minds in storage that we can wake up and they can help us.
