I did not get the Zemri's Key at The Achaemin Gate. Now All Rooms are locked

[RedBeard]

I attacked the brigades without talking to them and that old save is lost

 

I dint get any key

 

now no matter wherever I go all rooms are locked and I dont have the key.

 

where the hell do you get Zemri's Key: Dropped or given by Zemri above The Achaemin Gate. ????

The main floor rooms don't open unless you trigger the ambush in the north corridor. There is only one door to loot that is unlocked by the ambush.

 

Zemri's key is dropped/given by Zemri on the top floor. This only opens some doors.. Mostly the loot room on the top floo, a door in the southwest,, and the basement room.
