A few further toyings with the concept with the help of extensive coffeeconsuming.
*The beginning
The shipwreck would most likely have been a transport of some kind, slave, prison, leisure. Its nothing that I´m determined on putting much detail into, the person finding the shipwreck might as well be dead or otherwise nowhere to be found.
*Origin.
Considering the shipwreck being on the border to the Great Wildlands, she could be of Thukker ancestry just as she might hail from any other race. Speculated but left undisclosed, left as a possible hook for fiction when time comes that she would dig into her origin.
*Adoption.
By Minmatar couple of any tribe or seperate tribe. Commoners of lower class. She will not know that she was an orphan until the death of her fosterparents when she would discover the adoption records.
*General education
As gathered from the timeline and considering how the schooling system works in my country, she would have started aprox a year ahead than she normally would have and finished one year earlier, skipping over one grade but did not continue for college.
*Scarring, tattoos and gang involvement.
Her first gunshot wound would be simply due to having been at the wrong place at the wrong time, such as during a robbery at a shop or random shootout between the local rabble.
Seeing as its not uncommon for a teenager to become rebellious, she joined a local gang.
Second and third as well as other scarring would be from her time involved with a local gang, defending territory or other types of fighting.
*Capsuleer training through sponsorship of an unknown benefactor or drafted into the militia?
Could have opened her eyes more to the "worlds" outside of her home system. Opening doors that had been otherwise shut to her?
Curiosity in regards to this unknown benefactor and perhaps undergoing a search for him/her.
Minmatar militia, as previously noted interest for ooc-wise, she might be drafted or see something worthy to fight for as opposed to having been a gangmember in her past. Or that she may have been drafted for capsuleer program to fight for the Matari people. Or that she may have enlisted to get offworld- "Join the army, travel the world, meet interesting people and kill them!"
*The vastness of space and inexperience.
Instead of starting off as a knowitall she could have been isolated to a point on her "home world" perhaps making the occasional contact with offworlders that paid visit to her hometown seeking stories of their travels and exploits or read about happenings in Minmatar space or simply none due to lack of interest.
Up until entering and finishing capsuleer training, she had never experienced space travel(as far as she would remember anyhow) and hence exploration beyond her homeworld would be considered new experiences.
