How to get to Nightfall?

[pacoface]

I'm stuck here. I've done both caves in Bleaching Sand, flipped the switches and lit the torch. The ladder still has the flames at the top, so I can't get out that way. When I follow the instructions above and try to go west, Rowan doesn't want to go that way. I go slightly west then north, but the only bridges I find to cross take me to a little treasure chest I've already opened. I have no idea where to go from here.

Have you got the guide? It shows all switches that need to be put ON, so you can get rid of the blocking flames.
