Well my exo warlock is a character constantly filled with self doubt despite the fact that before and after death he worked much harder than any other warlock to discover the mysteries of the traveller, he never felt worthy to have life and ever since the ghost brought him back he has been trying to prove himself, but he feels guilty and thinks the ghost should have chosen some one else. He died while researching the fallen in old russia. My titan Exo started out as a servant to a rich human family on one of the outer colonies during the golden era, when the darkness attacked he managed to save himself but the family died, he has felt guilt ever since. He soon became a guardian of the tower hoping to gain salvation. He became a titan of great renown. He died attempting to rescue a group of awoken merchants who were fleeing to the last city. My human hunter was an outcast. Her parents settled outside of the last city and they set up a trading outpost for guardians passing through. But when she was a teenager the while outpost was destroyed. She was the only survivor and left with only a hand gun a sniper rifle and the clothes on her back. Over the next couple of years she did what she had to, to survive. But than one day she fell on heavy fire from the fallen and was low on ammo. Than a titan appeared and saved her but not before having her ghost shot down and receiving grievous injuries. The titan died in her arms. She tried to bring the titans remains back to the tower but was killed in old russia Not sure how lore friendly any of the above is :p
