My first mod so dont rip the hell out of me.
Extraction:- Place Hidden Chamber.esp into Program Files / Bethesda Softworks / date folder, load up the Oblivion start screen, click on data files then click on Hidden Chamber. Your ready to play.
The entrance is a well next to Cheydinhal Chapel, next to the small graveyard thing!

After wandering Cheydinhal looking for the next person to kill, you stumble upon a mysterious looking well. After closer inspection, you realise that it isnt a well, but a secret entrance to a long forgotten Hidden Chamber.


WARNING: THIS MOD WAS INTENDED FOR PEOPLE WHO HAVE FINISHED THE MAIN CAMPAIGN. IF YOU HAVEN'T FINISHED IT, YOU CAN STILL PLAY BUT BEWARE THAT IN THIS MOD ARE A FEW HIGHLY OVER-POWERED WEAPONS MEANT FOR PEOPLE LOOKING FOR FUN ONLY!WEAPONS ARE FOUND IN THE WINDOW-SILL CHEST IN THE BEDROOM AREA.

PS:- To make more use of the Torture Chamber I strongly suggest that you download and install Carcernus Prison mod from this site as it adds some spells that will help move people around. Also, Carcernus Prison is one of the best mods i've seen so far, and I am in no way trying to out-do the author:-)

ALSO - Guards CAN follow you into the place so either make sure that you have no bounty, lock the entrances via the console button (above tab) clicking on an entrance door and typing lock 100, or kill anybody that comes in lol! They can also come in through the portal room unless they're locked aswell :)
Easy way to get rid of bounty = Console + player.setcrimegold 0
or
player.payfine --- Will also remove all your stolen items so use with caution:)
Have fun.
