I assume they are, I heard this snippet of Toland saying some like this [i]”If you’re immortal what does,’What doesn’t kill you makes you stronger’ mean?”[/i]

To completely answer your question, one of the new lore entries in the book "ghost stories" contains a story of a ghost who couldn't find his guardian. He eventually gave up trying and settled with a group of humans on Earth. Eventually, they were attacked by Fallen and most of them were killed, including a child. The ghost, saddened by the childs loss of life and his parents tears, managed to revive the child. He later admitted that he thought this was a mistake because the child would never grow to reach his physical peak and would remain the same forever.
