Serpent Temple

I've beaten the naga, but immediately afterwards i'm stumped. How do I open the portcullis halfway to the room with the fountain and the chests, and how do I open the door to the right hand of where the naga was?

Struggles to remember geography - first one sounds like the opposite side of the door near the back entrance - it won't open. The one on the right of the naga - just go out to the corridor that you have already found, and go left, walking around that corner of her chamber. You will find the other side of that door, which can then be opened by either a lever or has a skull lock (not sure which). The main challenges (Lift maze and Elyssia) are down this way. Map out where your lifts go, as that saves on the frustration.

In the middle of the room where you first met the naga is a big decorative object, look carefully and you will see a lever/button thingy. This opens the gate to the fountain. Above the fountain is another one, this opens the gate to the maze. Both are easy to miss. The other door can only be opened from the other side, by the time you get there you won't need it.

I must have gone left instinctively, pulled the lever (cos dat watcha do wit leverth dat youse finds rite - Boogre blab), and just walked straight on round when I came back from the fountain room. I never noticed that the other way was ever blocked. Have had someone else ask me what to do there, and I tell him to walk around corner silly, what be your problem. Much embarrasment - need more wisdom - time I went to ASK SHINWIKI again.

I did pull the lever above the fountain, but the door to the right of where you kill the Naga is still closed, no matter how close I stand.
