Another short trill comes back at you and the sabotuers clinging to the underside of the docks seem to relax their guard, lowering their crossbows and rubbing their tired shoulders. The two swimmers also make their way to wooden posts and beams, and all four of them seem to hunker down and settle in to wait for the next step to occur.
The pair of guards that had previously been involved in a quiet argument have settled their differences, but one has walked away from the gang plank of the Lord Bingham's Belle down the dock and toward the other pair, who are still struggling to remain upright. The lone guard at the plank has flipped his pike over to drive the point into the wooden boards, and leans on it heavily.
The walker reaches a heavy bronze bell set in a sturdy wooden arch further along the pier, taking the knotted pull cord and giving two sharp tugs. The brassy clanging rings out over the docks, echoing back off the ships and water. The sleeping pair jerk with a start and glare at the bell ringer before going back to their naps. Much futher down the docks, farther than you can see in the dim yellow glow of the arcane torches, more bells clang out into the night as the other Dock Watch guards call an All Clear.
