Tor says to Sheldon and Indigo: "Ah, good work. I think we should follow those tracks. I think we'll find these headhunters we've heard so much about. Those wounds on the corpse are obviously from ceremonial weaponry, which means this person was an unwilling sacrifice, and probably either a captive or a slave. A willing victim would simply have walked into the vale, allowing the darts to hit him."
Merin nods. "Agreed, we should follow the tracks, but I want to sketch a copy of the painted symbols first. That might provide us with important information, if we show it to the right people."
