Star-sovereign

Star-sovereign is an outdated term for the leader of the Rephaim.

Description
The term was used during the rule of the Mothallah family, after which it was replaced with blood-sovereign. It was an English title the Ranthen created to refer to their former leaders. It implies they were sovereigns of the "stars," since Rephaim have star names on Earth, and that they were a guiding light and a means of navigation.
