Re: Chapter 1: The Road to Morgansfort
The party moves out from the eerie cell block and torture chamber, turning left down the corridor. They reach the top of the stairs and Gilly pauses, looking back at the others. Leleanne and Veskard point at the corridor heading north.
You travel north for 40 feet, finding no traps. Suddenly Carnalore whispers, "Stop!" She points at a brick on the corridor wall. Wyrran and Glanduil can immediately see what she's getting at. At the top left corner, there's a just barely visible jog in the line of the brick's edge, making a narrow rectangular slot parallel to the floor and about an inch long. It looks as if the slot would accept a coin, a dagger with a thin blade or something of a similar size and shape.
Glanduil nods, and speaks in a low tone. "It seems too regular to be a mistake, and they would have filled it with mortar. I'd wager this is the mechanism for a secret door."
Squinting into the darkness, you can also see that 40 feet ahead of you the corridor turns east.
In this ruleset, Elves get a chance to find a secret door with even "a cursory glance," and Carnalore rolled a 1.
