I only have 2 red parties left to kill off, and that includes killing off the king and his men.

I am in the southwest quadrant of the level, where there were initially 5 moving blocks in the main part of the room: 4 e/w blocks and one n/s block. By using the 2 n/s switches and one e/w switch, I have narrowed that down to just 3 e/w blocks and have killed all the parties in that room.

At (9,17) there is a n/s block with an immovable block to the north and a red party to the south. I cannot seem to get it to move. When I flip the n/s switch to the west of this block, it says "You hear a grinding sound as stone walls shift about" but that one does not move.

when I flip the n/s switch to the north of that block, it says "You hear a grinding sound that is cut short." and nothing happens.

I have tried several different steps with the three switches to no avail and can find no other way in.

I only have about half the gold needed to get past the troll, though that wouldn't matter as the last 2 red parties are in the room I'm trying to get to.

HELP!
