[X] Go straight. There are strange groves, yes, and there's the wild animals that apparently attack people without sense, foaming at the mouths, and the witches, and--wait, what was your point? Oh, yes, but it's the straight path, and even more importantly, it's the main road. So maybe they used it?
[X] Go right. You'd have to be insane to go through Corpse Woods, and anyone who steals the relics of a famous martyr has long since become unhinged. Plus, there are usually not... physical dangers from going through Corpse Woods. Usually, at least in stories, it's more about the mind and soul. Which is harder to shoot an arrow at, but at least won't outnumber you.
[X] The left route, which goes down at least a little bit, and is a little rocky and unsteady, as if someone had tried to build a stone road and given up, leaving it worse than if it was good, honest dirt. There were supposedly bandits (which they might be looking for) and beastfolk villages (which they weren't) in this direction. Neither are likely to be very trusting, even at best case scenario.
