Mech Pilot who has married into the Royal Family but is not prepared to pilot the Ancestral Mech.
Jozefina doesn't even make it out of bed before she vomits all over herself. She falls onto the floor, groaning and wondering why she feels like death. Her whole body hurts, especially her head. The light hurts her eyes, and they itch so bad it takes all her willpower to not claw them out of her skull. Her knees buckle when she tries to stand, so she crawls to the vanity and uses it to pull herself up. In the dim early morning light, she can clearly see the faint glowing lines growing from her pupils and out across her eyes.
She'll be told later that this is normal, that it's something every vestige pilot goes through. The great war machines weren't built for humans, and so they need to make changes to their pilots to make them compatible. Her anatomy will continue to shift until she is undeniably something other than human. She will have to spend more and more time inside the vestige as her body morphs in ways that make it incompatible with survival on the planet's surface. One day, she will be entombed within the great alien machine, functionally immortal as it keeps its pilot alive. She will be kept in that limbo until the day she is struck down.
These are all things Jozefina will learn later, however. In this moment, all she can do is heave again and pass out on the floor of her room.
