The passageway had extended in size all of a sudden merely to accommodate that gate. It seemed far too big to be necessary.
Strangely, too, the wood of the door didn't show any traces of rot. Nor did the iron brackets that bound it show any traces of rust. They would have struggled to move it if it hadn't already been opened a fraction, and from its sturdiness, it seemed impossible that they would have been able to break past it had it been locked.
That wasn't worth worrying about, though, not when the way forward was so tantalisingly offered. The source of the blue light was clearly coming from beyond the door. Even with it opened a crack, enough for three men to fit through, the angle of the door prevented them from seeing much of the beyond apart from a single stone brick wall.
