We awaken in the pool surrounded by the sleeping aboleths, greet a door, get around it. But when we attempt to see what’s inside some aboleths try to stop us. There’s a fight, we lose, and are dominated. You’d think more would happen, but that’s really just about it.
Oh, I mean also it was technically revealed that for some reason a cadre of aboleths guarded the sarcophagus 4000 years ago and ordered it to be taken to Xxiphu, their temple. That might be important. Sadly no one knows that.
