The spider attaches a spray of net-light webbing to the handle and attempts to pull the door open, bracing it's legs against the side of the door. "Locked, I think." Merla says, in a distracted tone of voice. "Let me try the other." If the spider has no luck, it drops down and moves around to try the door on the other side of the corner.

Failing that, Merla sends it scurrying through the archway and has it follow the wall on the right-hand side, moving down through the tunnel-like extension, all the way round towards the wooden door.

The map doesn't work for me, says I don't have permission to access it. The spider has has a strength of 7 if it's relevant, although it won't try to force the doors if they're locked or jammed.
