Need help freeing Valdane in Naga

[Fang]

I've killed the queen got the skull key and regen robe and gone thru the entire dungeon again but still can't find the way to open up Valdane's cage.

The grate on top and the cage in the maze is the only 2 I can get to and he says this is not the way each time.. I have the Gold key and the skull key. Have never used the Gold key for anything I don't think. Skull key opened the door to Relic which was useless. Already had relic from jumping up from water and pulling myself up. I hear some people mention a Silver key in the Naga Queen area but all i found was the skull key. Same thing?

I'm guessin one of the gates I can't open is where the gas mask is at which I didn't need.

I've mapped the whole place out and there are 3 locked gates I don't know how to open. First one is after you grabbed the Sigil then you head south the only way to continue the dungeon and there is a metal gate with no locking/lever mechanism right before the water on the right side. Don't know how to open it.

The 2nd one is just north of where you are standing above Valdane.

The 3rd is right when you come up the stairs from Valdane's maze the first room south is some Treasure chests and a metal gate heading west with stairs leading up.

I got a skullcrusher mace from Naga queen, I'm thinking of using it on myself to end the pain.

I was in same spot yesterday and saved it then patched it today and vola couldn't load game today to continue (..

Please help :)

Pretty sure the gold key was in the Prisonmaster area with the wooden ramps and the 2 side coves atop ramps, one had a naga fountain in it. The key was at the deadend after going up the ramps, think it was on a short stone pillar.

Gas mask was in a dead end room that had a lever on the right wall as you enter. Was in a chest along the far wall, not sure but maybe a square firepot or some fountain was in middle of room.

You have to jump over the drop floor to get to his door that you can open with the gold key.

At least you found the temple. I got lost, finally came across that guy you have to kill for the fighter quest, the one where you save Falen or whatever. Now I've made my way to the top of a mountain and I'm trying to decide which side to jump off. Gettin kinda tired of wandering around in the woods.
