Go to the farms

You take the old road, across the green and golden fields. The wind carries a mix between the flowers and the stink of the farm animals.
In front of you, you notice a big cluster of houses and the main stables.

The Stables:
Horses and sturdy farm beasts are outside, and the owners of the place are busy with chores. You can get a mount to cover more ground and arrive at the stone before the night catches you.

Ask for help at the big cluster of houses:
Further down the road, a cluster of houses, with a rustic tavern, and a big farm down the road. The people there might know something or you can try to investigate the area.
