How do I get the second cristal soul, on Angierach? (spoilers for Avernum 2)

[Eduardo]

I got a Phoenix Egg and all, went there, killed everyone. But, to get to the room that I presume the Crystal Soul is in, the "containement chamber", I a certain key, but I have no idea where it is! I have roamed all over that place and I found nothing! I'm completely stuck. How the heck do I get that damn key?!

You need the Lich Key hidden in the Chambers of Rakshashi behind a hidden switch.

where are the chambers of rakshashi?

[Randomizer]

It's a south section that is east of the cell where you were imprisoned. It's been years since I played so I don't remember which side of the Crystal Soul room it is. There should be a sign or at least a rakshasa that you fought to identify the rooms.

Been a while here too but iirc it's down towards the bottom right of the map square

It is in a room in the very bottom very right part of the map.  You have to defeat an opponent and press a hidden switch with tool use nine.

[Eduardo]

is it a regular hidden switch, or I need to do something to be able to activate that switch? I've been looking around all of the south part of the map and nothing!

[Eduardo]

where is it on the mini-map?
