It's off-handedly mentioned post-MSQ by the person who introduces you to the delegates that people are still transforming even though the Final Days were stopped, though whether because of lingering negative dyanamis and/or the beasts themselves is anyone's guess.

I'd like to hope they don't gloss over the matter and that the beasts continue to be a problem in 6.x MSQ bits or even further beyond because it's not like everywhere in Aldenard had a sizeable and organized military force to curb the problem like the regions we dealt with.
