Can anyone answer this? I think I asked something like this last week but nobody had an answer.
Do the reapers/catalyst give a shit about the organic/synthetic chaos raging in other galaxies? Or are their actions only ever involving the Milky Way? There's no way ultra-synthetics(even stronger/more superior than reapers) from other galaxies wouldn't have risen up and been able to find their way to the reapers and dominate them(maybe not yet, but it's probably inevitable).
The nearest interesting galaxy, Andromeda, is two and a half million light years away. That is ridiculously far.
