"With that, we should be done."
In the end, my solution to the problem turned out to be slightly different than what I initially imagined. Instead of just shielding the budding civilisations from the great filter aimed at eradicating them, I decided to send several tens of copies of mine to each of the promising worlds. Rather than acting from the level of an all-powerful being, I decided to bring change from the ground up.
In general, great filters weren't a physical thing. It wasn't some kind of apocalyptic being attempting to eradicate all life. It was just a name given to a natural occurrence that early civilisations could not survive. Back during my life on earth, humanity had yet to officially make any contact with an alien civilisation. And the great filter theory aimed at explaining this lack of other forms of life in the universe.
