Umm, where do you find out your character died pre golden age? If the ex bungie employee AMA was real, this starting area was originally the start for exos only. Exos were created in the golden age. But, if you reject that, there is also the grimoire card about the awoken, that says they are unfriendly to earth born awoken. This means, your character could have died post-collapse in the cosmodrome. Because there are earth born awoken.
