Lore question about Guardians who died in the Red War
Okay so here’s a scenario
Ghaul: *entraps the Light*
Guardian: *gets killed*
Ghost: *does survive but can’t bring them back*
*few weeks pass*
Ghaul: *gets defeated*
Ghost: *gets the Light back*
Could that Ghost go back and revive their Guardian?
Yes, it should be possible and I believe there is even a lore tab that implies that. As far as I know, the only way for a Guardian to permanently die is to kill/incapacitate their Ghost so they are unable to revive them, or simply not have the Ghost revive them again.
