I think you should all pretend there was a major battle that got so close to the Last City and if it weren't for the Guardians who've we've said goodbye too, it would have fallen to the Fallen and all the other dark forces out there. Instead of weeping over the loss of your closest Guardian rejoice as their sacrifice has not been in vain. "As a Guardian didn't need to speak, but now that their gone the Last City will speak for them and bring amongst a new generations of Guardians to rise against the darkness and defend our home! Each of the Guardian's Ghosts may morn your hero's death as they have grown close in our short journey. But now your Ghosts live and search for someone who can hone their craft and acquire new skills worthy to carry out your name as if you, yourself, was the instructor"
