Personally. To drill home the loss the red war campaign was supposed to elicit. I’d imagine that any dead guardians from that period are D E A D. But. I don’t know if the lore especially covers the question. About the dead guardians from the red war if their ghosts somehow survived. We have had lines of dialog in the game talking about how [x] is truly gone because there’s no light left in the ghost. Or the body. Like [i]there’s nothing we can do, there’s no light left in them. [/i] And when the red legion trapped the traveler it would seem that it completely cut us off from the light. Save for whatever our ghosts had in reserve. But then the bodies would have been cut off too so they’d be lightless corpses. Then again I think some lore suggests that a small spark of light is present in most life. So maybe it’s there in death. So honestly. I have no idea. Though back to my original point. Our ghost was all kinds of messed up during that battle. I doubt he would have survived for long, solo.
