FFXII Tomb of Raithwall

So I managed to kill the second Demon Wall (skipping the first) and then I activated the two crystals on the north and south side (so those teleporters now work), but now I don't know what to do. Walkthroughs seems to suggest that some passage is supposed to open up but I never got such an FMV.

Could the fact that I never defeated the leech bosses in the south have an effect on this? I spawned them but they proved too difficult so I ran away and saved. When I restarted my game a few hours later they were no longer there. What am I supposed to do next?

I'm afraid I can't help you, I'm far too much of a fag. If anyone on here isn't a huge fag, maybe they can help you.  If no one helps you, I would presume, if I were you, that everyone who didn't help you but could have was too busy thinking of potential cocks they would like to suck.

I've figured it out, this altar kind of thing lowers itself when you activate the two stones. So now there's an open passageway, so after healing/saving, you can teleport back to either of the two stones (green or red) and then proceed down that path to continue with the game.
