I'll put it as short as possible, but here Elizabeth's lore and some fun facts: Eli used to be in the elite ranks in the Octarian army due to her master skills in Chargers and combat adaptability. She was sent away to a camp at 16 to polish everything she knew and train restlessly.

There is where she met Joik, and both fell for one another at first sight. However, in one of their usual meetings, they heard about others managing to escape the underworld and got curious. They wanted to see what was beyond and around them.
