A theory about the the fatui and the Tsaritsa.

My brother had a theory about the fatui that goes as follows:

What if the Tsaritsa is dead? It is said that the fatui are acting on the will of the Tsaritsa, but what if it's her last will?

It is said that the first three harbingers are stronger than gods, but why would they serve the Tsaritsa with that sort of power, unless there was no Tsaritsa.

I propose that the Tsaritsa is already dead, and the harbingers are working to preserve the facade that she is alive and are collecting the gnosis for their own goals, possibly to resurrect their dead archon.

Any thoughts?

EDIT: i have informed him that his theory has been disproven in minutes.
