I like it. It sounds very promising.
Personally, when I don’t yet have a title, I give a project a codename for convenience. Chrono Club was Project Legacy, Kirano (which I have yet to talk about) was Project Turtle, that untitled first part from my trilogy is Project Lorax, etcetera. What I’m saying is maybe consider giving a codename for the time being so we have something to refer to it as. Maybe Project Starthrones as a nod to that R.R. Martin inspiration? It’s not really important what you call it since it’s temporary. Have you thought about the actual title?
