Are you really sure you wanna do this, Hannah? Overseer Buchanan asks her skeptically, his wrinkled, greying brows furrowed with concern as his voice echoes off of the Vault entrance's steel-and-stone entrance. We don't know what's out there... And I'm not certain you're equipped to handle whatever waits on the other side of that door. We could always send Brody out there instead, he suggests, his voice almost pleading as he gazes into Hannah's blue eyes.

I'm sure, Hannah replies confidently, placing a hand on her hip and smiling with a daring expression. I wouldn't pass this opportunity up for the world. Just think of all the cool stuff I'll find, all the discoveries I'll make. It'll benefit the vault for sure! Her eyes sparkle with childlike wonder as she imagines all the possibilities that await in the world outside their sheltered existence, all the new developments that might have come around in the two-hundred years since nuclear armageddon.

Overseer Buchanan eyes her for a moment, his eyes scanning her soft body and unmarked complexion for a few moments longer before clicking his tongue and shaking his head skeptically. Very well, he replies, unplugging the switch from his Pip-Boy and slotting it into the door controls of the Vault's enormous, cog-shaped seal. He hovers his hand over the big red button before adding: This is very important work, Hannah. If you don't find that chip in a month's time... We could all very well perish.

Hannah nods with determination. You have my word, Overseer Buchanan. I'll find that chip, don't you worry. She looks over her shoulder at her parents, who stand behind the guard rails, both of them holding each other with tearful, fearful expressions. She smiles confidently and winks at them, assuring them that everything will be fine.

Overseer Buchanan gulps. Alright, then, he murmurs. We're trusting you. The fate of the entire vault is in your hands.

He presses the button, and with a few bursts of steam and a droning alarm, the walkway to the Vault door extends, and locks disengage. The door rolls to the right, exposing the stone cave walls of the exit... And Hannah daringly approaches. But before she leaves, she turns to face her parents with a soft, reassuring smile. Bye, Mom and Dad. I'll see you soon... And I love you both.

Her heart flutters with excitement as she walks along the catwalk, coming to a stop just before the threshold... The point of no return, the gateway into a brave, new, unexplored world. She hesitates for a moment before stepping through into the cave.

Alarms sound out once more, and she turns just in time to see her parents crying into each other's shoulders before the massive iron door seals shut behind her. This is it... She's really doing it. No going back now.

Hannah turns towards the cave entrance, light peeking through the boards covering the rickety door to the cave. A few strides later, she's gripping the handle, pulling the door open... And is immediately blinded by the light as the sun harshly greets her for the first time in her life. As her eyes adjust to the stinging and brightness, it sinks in... She's making vault history today. Nobody else has ever been outside since the first arrivals... Except her. With a newfound sense of wonder, she opens her eyes.

...and is immediately shocked. Down the side of the mountains are... Buildings, stretching for miles. What used to be buildings. Now, they're half-collapsed, charred husks, partially overgrown by ugly, parched plants. It's horrible... Like nothing she's seen before... And she finds herself getting a bit scared. But she reminds herself of the overseer's words: the fate of the vault is in her hands. She gathers her courage and begins her trek down the side of the mountain.
