The note from the miners was short and specific, and included a simple map. The downward-sloping tunnel wasn’t that difficult to drain, at least enough to get through, and what they found on the other side was a surprise. It was obvious that the natural tunnels provided access to an improved, albeit likely ancient, set of larger tunnels. When they explored deeper into the hillside they found evidence of mining activity: a few tools, supports, and other long-forgotten implements and constructs.
It seemed that the spider tunnels connected with the end of a horizontal tunnel, probably the northern end of a set of improved tunnels. Coming topside, they searched among the hills and trees and found, about 1/2 mile to the south, a collapsed mine entrance, buried under rubble and dirt, with trees growing through the heap, obscuring it from easy notice.
The men believed that the old mine was of human construction, and probably hundreds of years old. Beyond that, they had little to add. They’d found evidence of living creatures: filth, more webs, and other refuse of beasts. After the death of Allyn they were unwilling to go any deeper into the tunnels without support – and who could blame them?
Prince Oargev, two days after his meeting with G’Toch, again dispatched Amarack, Deaton, and Luc to investigate the tunnels and, if possible, clear them in order that mining could begin. If precious metals or gems were in those hills, New Cyre would profit mightily.
You’ll have had two days after returning to town with G’Toch and getting back together with Deaton before the prince calls you to his house again and hands you the note and map from the miners. The map is pretty rough, and is only meant to show the openings relative to one another, and the tunnels that connect them underground. They’re not moving any deeper into those places until more muscle shows up.
