I've finished all of A1, except exiting Avernum and have hit a roadblock. I went through the contacts for joining Scimitar and destroyed the Orb, but when I returned to report in, the contact in the Bargha secret room was no longer Cleese, but one labeled "Assassin" who attacked the party. Additionally, all the other NPCs in the Scimitar base behind that room were hostile. I don't recall killing anyone who might have turned them against me. I've only killed the assassin thusfar and have tried coming back a few days later, but they are still hostile. I am not getting any new dialog from Calder indicating that anything changed. He still just tells me how to get to the secret area. Any idea what may have happened? Did I do anything out of order for the quest that may have caused this?
