Whatever her permutation, she conforms to an archetype. A variation on either the “princess” in distress, or the reassuring, supportive mage or healer found primarily in role-playing games (notably Japanese titles like Final Fantasy, Dragon Quest, or EarthBound), she is more or less enslaved to work on your behalf. She fills in the plot with valuable intelligence, pulls strings in the background by overriding locked doors, and pilots vehicles to usher you from place to place. She serves you, or she serves the story. As such, she sets the stage for you, hero.
