Dal Shabet

All this time, Amos was racking his brains trying to figure out who the bones belonged to. Was it some traveling adventurer? How did he die? Why did he take the stones? What were these remains doing there, and why were there stones inside them if the room, as well as the left door, looked like they had been used? Or was he the last person to use these ruins? Maybe he wanted to take the stones with him so that no one else could get in.
