Sounds like something that could be worked into a bottle quest.
The vyrewatches have started looking for new sources of blood, and have landed their gaze on the hardiest of warriors: The Fremenniks. Unable to cross the Salve, they set off in the direction of Daemonheim, knowing that it is inhabited by fierce warriors from the Fremennik province.
Turns out, they didn't consider the higher-than-usual alcohol content of their new blood source, and drunk vyrewatches are now bothering the inhabitants of the northern parts of Morytania.
It is now up to you to help those poor inhabitants (werewolves, ghosts, and other "helpless" individuals), and find your way to their lair where a certain head-strong Fremennik has become the unwilling center of attention for the drunk vyrewatches.
