At some point Mira and Alexia was separated by starship crew. They didnt like a stowaway at their ship so they left Mira on a nearest civilized planet. Mira tryed to contact Alexia but she was fired from the ship. Contact was lost. 5 years past since then.

This is how their reunion probably will look like. It didnt happened in the game yet but GM gave some hints it'll happen soon enough.
