Yes, yes! This is a very in-depth take on the Epura. I'm so happy that it's getting a lot of thought put into it such as this! You're definitely going to see more of it in the future, especially with Cooper (since he's already infected). Hopefully he doesn't cark it like Dia! Poor thing.
And yes, they will absolutely die in a few weeks if they don't find a way to move it. Though, it's covered the planet like an ocean so even if they were to find a way to remove some of it, they're still pretty much screwed lol. Thank you so much for this comment, it's made my day! <3 <3
