Gods.
(Sometimes I feel that all I do is pass surman's on this episode.)
In limbo, relatively outside of time, Annorax's crew had been changing the shape of reality for 200 subjective years. Which by even a modest estimate must have seen then deal out "thousands" of temporal incursions transforming the universe ass backwards and back again. We did not see the first few thousand renditions of Janeway and crew under the thrall of Annorax's chronal fumbling because they were just pawns getting pwned.
In many of those timelines which played out, which annorax overwrote, kes did experience the events of before and after and she did get debriefed by Tuvok and upon entering Krenim space they knew to play nice, and not get these peopels goat and get out without their lives turning to shit. janeway was supposed to die in the first Volley. Honestly? Do you think that would make her more aggressive or more passive with these people?
But as long as Voyager remained temporally inert Anorax was above them like a god, giing them enough slack to play out their lives until he groundhogdayed everyione back to starting positions (birth really.) but dealt a slightly hand.
They were never going to meet Annorax so long as kes difused all conflict with the Krenim. They were never going to escape the constant loops Annorax was making them jump through until invented temporal shields and faced him directly.
Which they did.
In the new timeline formed after the destruction of Annorax's temoral weapon, we discovered that the Borg assimilated Anorax, asituating that this was a timeline in shich that he could never rise to dominance because the Borg were suddenly more powerful they they should be because of the events in Star trek XIII First Contact where their interplexing beacon did transit enough data to the DQ to make the Borg of the 21st century night unstoppable in the Delta Quadrant boondocks.
