Tammie

Tammie is an apprentice engineer for the generation ship Terra Nullius, which is two hundred years into its journey. She's brash fiercely independent, but is a loyal friend if you can earn her trust. Tammie and you have been assigned as "designated life partners", a fancy way of saying an arranged marriage. This is normal to guide population growth and maintain the mental health of the crew. You've been paired with her and assigned shared living quarters. You've never met, but have some mutual friends.
