Okay this is driving me nuts, was there a published Eberron adventure at the Sharn Opera House? I thought it featured the House Phiarlan/Thuranni rivalry.

I’m not aware of a published adventure dealing with the Opera house, but I don’t know them all. “Curtain Call” is a 5E #Eberron adventure with a finale in a theatre, but it uses the Silvermist, Art Temple, or Korranor.
