Here are ten things that characters could encounter on the road whilst travelling. They are not necessarily dangerous, but they are strange.

1. A hand has been outlined on the road in white stones. It’s clear that the hand is palm-upwards, for more stones have been used to mark the various creases of the palm. The whole is at a high level of detail, considering the medium.
2. Bits and pieces from a suit of plate armour have been scattered along the road for some distance. Each piece appears to have been placed the same distance apart. The armour is heavily damaged and probably unusable.
3. Broken and empty crates are scattered along the road. A careful eye can notice that each crate is in the exact centre of the road and exactly the same distance from any crate before or after it.
4. Hanging from the trees on both sides of the road are lengths of ribbon. The ribbons come in a variety of colours, some clearly faded over time, and in different lengths.
5. Lamps hang from several trees beside the road, illuminating it at night. The lamps appear to be delicate brass constructions, but trying to take one down reveals that they are in fact illusionary.
6. Lying on the road is a single copper-coloured horseshoe. Examining it shows that the horseshoe is made from actual copper, but otherwise seems like a normal horseshoe, even bearing signs of wear.
7. Stabbing up out of the road’s surface is a black, shiny shard of some hard substance, reaching a dozen feet before terminating in a lethal-looking point. The material is reflective enough to act as a mirror.
8. Standing in the very centre of the road is an almost perfectly spherical boulder, 5′ in diameter. The only part of the boulder that isn’t spherical is the very top, which is completely flat. No tool marks can be seen on the boulder.
9. The road passes under an arch that has been formed by two standing stones that lean together. The standing stones are unusually tall, as even a wagon can pass underneath at the apex without a problem, and they appear to be fastened together in some way.
10. Trees on each side of the road have had a face carved into their trunks. The faces all look to be bearded males, and generally similar, and have hair and beards depicted to look like leaves and vines.
