Who is Cayde?
I would love to have Cayde back, but I just don't see any way that they could do it without basically destroying the lore of the game. Like if they can bring Cayde back, then why can't we bring back the hundreds of guardians who died during the Red War? Like maybe if Cayde was brought back as a new exo that could be cool. But I really just can't think of any way he could be brought back that wouldn't destroy the lore.
