"Falcon, have you any skill in designing or preparing traps? It may be wise to install pit traps in each of these huts/shelters in order to trap whoever should return to them. If we dig far enough down, say under the entrance to each hut, we could get to the sludgy sand closer to the water. It will act as quicksand and hold them in place if they were to fall through our trap. It's nothing fancy should be pretty easy to set up. 6 feet down ought to do the trick. It would seem Tfop is smiling upon us since they left us a bountiful supply of tools, arrows, and even a plow. All these items should help us prepare the traps."
"It may be wise to rig the pier as well. If we could mount some spears or fishing hooks under the water by the docking area, it may cause enough damage under their hull to break their rudder or even poke some holes large enough for their boat to start taking on water. This wouldn't kill them; it would simply prevent them from escaping and telling anyone else we're here."
