We don't know the state of Origin, though the fact that the Lurker has invaded Origin derived materials is a bad sign. We know that the use of Amps and Manips on a large scale has become impossible. And We know that the Lurker will continue to subsume this galaxy and no doubt others.
Well, it's hard to tell. Seeing as our original plan was to create a supersized ghostship and pray that it can wish away the Eater of Stars with sheer amp power. But there's no telling if it's still viable now seeing as we've halted trafficking operations and are using the kidnapped as colonists instead, along with the possible lingering Origin Tech instability. The Lurker is probably powerful enough to kill them all given enough time, seeing as it's practically a god in it's own right rather than a flawed demigod, but seeing as it is in its nature to spread, by the time it wins it may be too hazardous to kill Morul. Or it might have even just started using the people in the region consumed by it as conduits as well. Or maybe have gained enough control over Origin if it's currently assimilating it (which it may or may not be) to just use the Eater of Stars as a conduit.
Right now, running seems like the best option. I mean, and this is OOC knowledge only, but seeing as the Lurker would win in a fight against Timmy and our most cutting research revolves around Timmy, standing and fighting doesn't really seem too much like an option. Besides, the universe was destabilizing already (which was known IC), so it's not like finding a way to kill or banish them both would make everything better again.
Welcome to the universe. Everything is ruined forever. Please enjoy screaming while you still can.
