The first few hours he spent in the tunnel, Arran encountered nothing even the least bit interesting.
The tunnel wound slowly downward, ever deeper into the mountains, with other tunnels occasionally joining it. Whenever this happened Arran left small signs to guide his way back, marking the stone walls with his sword and setting Shadow wards that only he could see.
Yet although the tunnel was clearly man-made, he had still found no sign of either its creators or any others who had passed through.
The rough stone walls were bare, with no marks other than the ones Arran left behind. And while the air was musty, its staleness was a lifeless one, featuring none of the scents and stenches that would suggest people had passed here.
