Do you swear you won't use our worst fears against us?
There's nothing like suggesting the best way the DM can wipe out his players.
I predict that we choose to go into the forest to forage for food. It's difficult work, but we find food items (berries?) worth bringing back. We may encounter wolves or wolfen (and all survive, hopefully). I think we could try to avoid predators (or rather, scavengers?) if we don't carry any meat back. That said, being able to toss out meat as bait might help. But as there are no extradimensional spaces to store said meat..., that's probably not practical.
The above is what I hope would happen in a fairly straightforward campaign. If there are going to be twists, then...
One of the worst things I could speculate is that can happen is that we encounter wolfen, who convert us into wolfen as well. It's like a TPK, but a lot more fun for the (evil) DM.
An unlikely event is that Beren's creek is assaulted and overrun while we're away, but that'd just be really sad.
