Well, it being WFRP and most of your players being new, perhaps the first sessions eschew epic notions in favor of a little bit of driving home that it’s a crap sack world and your choices are black and dark gray at best. Also, if I recall early characters are not exactly heroic in capability. Some ideas

-Peasants complain of witches. When the witchhunters come to town halfway through the players doing their thing, the cure may be worse than the disease.

-A series of (insert faction) raids is causing the baron to raise his levies. The players get to help. But raising the levies involves things like special war taxes and dragging away unhappy peasants.

-Bandits! But very Robin Hood with demonstrable reason to be upset with their overlords. But actually a Tzeentch cult.
