If I recall correctly, it leads to the stairwell down from upper to lower, close to the T'Rang teleport. I had my first spellcaster with set portal place one at that teleport (and was that stair down easy to overlook! I finally chased down a spoiler to find the way, and still almost missed it).What lock does the switch that's fairly close to that particular stair control? I was sure enough I'd tripped it once before that I didn't flip it the other way in case I needed whatever it controlled to stay the same way. Maybe that is for the trap door and I never had found it before this current visit?
