Wayrest Case Files 03: Arrows Pointing Inward

For the last case of season one, we follow the road into Wayrest and look at three signposts.

The map records the correct directions as → ↑ →. On site they read ← ↓ →. Dents on the back of each sign show they were never swapped with one another.

The question: which signs were turned?

Answer (revealed in update 9): C — the first and second.

Each of those two was turned half a circle; the third is unchanged. The evidence tells us which two moved. Who did it, when and why, it doesn’t say yet.
