Any idea what the whole Europan Ice War is or are you just as clueless as I am
at most i can tell it's just a branching narrative that people seem to like to roleplay as if it's actively happening. It's set in a world where humanity has lost Earth (named “Terra”) due to global warming, terraforming/transforming other planets in the solar system (most notably Venus and Europa, from what I've seen) to live on. for some reason the people on Europa (Jupiter's least massive galilean moon, famously covered in ice) are battling against something else living there (non-human creatures?) and so they are just always battling a never ending war (“War Forever” being something people continuously say in these roleplay posts).
The rest of the posts seem to comment on the privilege of comfort versus being in the never ending War of Europa; e.g. soldiers on Europa continuously mocking anybody on Venus, and their love for warmth. I've even seen a post where one of the Europa soldiers finally flees to Venus, to comfort and safety, and yet he still can't sleep without the the cold of the freezer; “You never really leave Europa.”
i.e. it's a branching roleplay narrative (you could also call it a consistent bit that seems to gain story with every in-character post added to it) that seems to comment on themes of privilege versus war, coping with mental instability & having physical stability again, and the inherent cosmic horror of fighting an incomprehensible horror on a foreign ice planet (foreign to us, the viewers) oribiting Jupiter.
