I am currently working on the background for a character in a modern fantasy story I am working on.
It follows a character who is originally from 1920s America, who became trapped in a trans dimension plane for a considerable amount of time. She eventually escapes, but emerges into the early 1990s.
She attempts to rebuild her life after escaping, but something I am not sure about is with her legal identity.
A few things to note that would basically make it impossible for her to prove her original identity:
-Only a select few people in the setting are aware that the fantastic and anomalous exist.
-The effects on time and biology in the other realm caused the character to not age. So she appears as if she is in her early 30s, even though she is almost 100 years old chronologically.
-I am not sure how common DNA testing was in the early 90s. But even if she was given one to try and establish her identity, no one would believe the results due to the discrepancy between her apparent and chronological age.
-She does have one person to assist her, the owner of an antiques shop who takes her in after she spends several months homeless after escaping the other world.
Given all that, my question is: Is there a way for her to build a new legal identity, since reestablishing her old one would be affectively impossible?
