(Excuse me if this is poorly written it is actively 2 am lmao. Also I have a tendency to ramble out of excitement, so just a heads up 😭).
Something I think would be a funny/ interesting theory/ headcanon would be Erid having two sides. One is full of life and potential, where the Eridians and Grace live. The other side is the blood ocean😈.
In my mind I think it would be ironic if the ocean in Graces biodome is connected to the blood ocean but the Eridians never knew. Eridians are pack creatures, they don’t need much to be happy. So when they saw how fucked up certain plants were and how things were dying (not the stars, the actual plants and living things on Erid) they built a huge dome over the “safe” land they had left.As this infection/virus grew that’s when the blood ocean was created and destroyed all/most plants.
Eridians KNEW it was a problem but it wasn’t harming them…so they ignored it lmao. NOW Grace is here and the ocean they had was still normal so they built his biodome over it since he liked the beach (thanks Rocky). It’s fairly deep like a normal ocean, so Grace nor any Eridians explored it (I think it would be funny if Eridians just sunk…yk like rocks).
So, we all know Simon was sent down to gather shit and encountered the alien fish god. What if instead of attacking it, he found a hole in the ground and managed to get the sub through? Obviously the sub gets damaged and banged up so blood/water fill rather quickly. But by some miracle, the sub managed to reach the surface due to the difference in blood and actual water (buoyancy is what I’m trying to describe).
Now we have a sub in GRACES BIODOME. Obviously everyone panics but they get Simon out!
Now we have a BloodyMary!
(For extra context: the top side of Erid faces stars and Tao Ceti. Plus Erid does NOT rotate like earth, so the top side receives all the love and care. Meanwhile the under side is filled with virus and a potential death threat. It does not receive the same treatment and lost its stars faster since it doesn’t face Tao Ceti. When Simon arrives to this planet he figured (just like everyone else) that this planet is just straight blood. And due to its size and a whole ass blood ocean, people there just figure that the blood ocean is all that there is…obviously until Simon “stumbles” into the normal ocean on Erid).
