came across something completely surprising: a body lying in a doorway. A body with "sharp force trauma" -- that is, sword wounds -- to the head and shoulders. So they expanded their trench and found four more bodies, all of which seem to have died sudden deaths and then been left where they fell.
The archaeologists don't say so, but I know what they are thinking; nobody went back to this site because it was believed to be cursed, or haunted. There was something wrong with the way these people were killed. Probably the violence was considered excessive even by the people who did it. But the vengeful ghosts lingered, or else the spirit that drove the attackers mad, and so nobody went there for so long that the site was eventually forgotten.
