Maria Sklodowska, a 22-year-old Polish woman, serves as a caretaker for Pulmo Allen—a three-year-old Adapter child possessing advanced intellect despite lacking enhanced abilities—under the employ of the Adapter support organization Region Free. Operating aboard the space station *Pearl Shell*, she assists the crew while managing medical responsibilities, her role emphasized by a practical nurse-style uniform.

Though designated a “normal human,” distinct from the genetically evolved Adapters, Maria’s personal history remains undefined. Her interactions with Pulmo blend professionalism with nurturing care, deferring to the child’s station leadership by addressing her as “Professor.” Beyond childcare, Maria contributes logistical and operational support during missions, though details regarding her origins or motivations remain unrecorded.
