"A threat to the steading…"
On a 7-9 in spring or autumn, or a 6- in summer, either introduce a new threat to the steading or have an existing threat advance towards impending doom.
The threat you pick can be internal or external, imminent or distant, uncaring or actively malevolent. It might be either supernatural or mundane. But it must represent a threat to Stonetop, now or in the future if it goes unchecked.
Decide how you'll make the threat (or its escalation) known to the PCs. Will it manifest as a crisis in the village? Will a hunter stumble across it in the Wood? Will someone have a portentous vision or dream? In spring or autumn, consider tying the threat to the seasonal gain. Like, maybe the same merchant who brought an unexpected bounty of grain, herbs, and textiles also brings news that Daedra the Red's gang have taken up resdience in the Ruined Tower. Or maybe that troublesome hagr attacks someone down by the Stream but it leaves a clear, muddy trail back to its lair (a valuable insight).
