The return of Mirkul and Baal did not go as they had originally anticipated. All this greatly weakened them. With Bane, the situation is rather incomprehensible, it is possible that he also lost some of his powers. It is possible that The Dead Three are hoping to gain more power by uniting.
They could have done with a less generic name then.
I agree. However, I personally do not support the theory that the Absolute is The Dead Three. It seems to me that the Absolute should be much more strongly associated with the illithids.
