The Vault knows its denizens well.
I don’t want to be alone, whispers Dream’s soul. But he is. And the isolation curls so beautifully around him, the walls of obsidian and the rush of lava muting the outside world, warding it off like a salt circle, but this is no protection.
The obsidian cries the tears that Dream will not. The lava hisses pain and fury and thinks to burn others and burn itself and slowly cool into that same obsidian when it strikes against the river of sorrow flooding the land, fear and wrath and grief frozen and immortalised forever. Loneliness becomes Dream, makes him beautiful.
You are mine to keep, says the Vault.
I fear not being in control, murmurs Sam’s heart. And so he isn’t, not really. His control is a child’s game, a bloody one, pulling the wings off flies and watching them stumble about, slowly dying. A sandpit in a playground, piled up high and decorated with pebbles, and sat at the top is the king of the castle. This power is temporary, transient, fragile. The house built on the sand will not stand strong against the wind, the rain, time.
The Vault adores its Warden. Sam can have his control for a while, think that everything is within it, the prison a snowglobe on his desk that he can shake as he likes, just to watch the glitter unsettle and resettle. Encapsulated in this perfect world, he does not see how it’s driving him to tie himself in knots just to keep it how he wants it. Perfection is unattainable, and yet it’s so often sought. This is easy to take advantage of. Sam’s a good Warden.
You are mine to control, says the Vault.
I want to go home, breathes Ranboo’s mind. He never will. They’ve already been taken, already crossed the border, been sent over the river and eaten the pomegranate seeds and taken into himself the sustenance of the dead. They stand there in his cell, waiting, waiting, waiting, and he is standing in his grave, but he doesn’t know it, not yet.
The Vault likes it when they don’t leave it, when they never manage to leave physically. Not that they ever truly escape, but a predator enjoys the allure of prey that do not see the trap as it snaps around them, do not make it flash its signals and draw them back. Ranboo stands in his cell, in their grave, in a mouth. Death is one slip away, down the throat.
You are already home, says the Vault.
I fear being unable to change, admits Quackity. This is an interesting one; most fear change more than they do re-creation, but Quackity has reinvented himself many times over, stepped into many costumes, put on many faces, and stagnation is his worry. No, deeper: to not be his own creator.
The Vault croons over this friend-lover-leader-politician-follower-enemy-torturer. The artifice of the self is an intriguing thing, and it does so love the pain that Quackity echoes in his every step, his own, others’, blood welling in the footprints sunk into the mud of the land. Quackity invented himself into a part of the Vault, and now he cannot shuck off this role.
You are my creation, says the Vault.
I don’t want to die, they all beg. This is the oldest fear, born from a long, long time ago; the Vault knows it well. How to use it, how to drag it out, how to make someone fear and revere it. It can make death a better place, if it wishes. Or a worse one. One who has been consumed still has to go somewhere, after all.
Life and death, fear and anger, joy and grief - they all circle around, chasing their own tails. The Vault knows this well, too. It takes it all, everything. The Vault has been used in many ways, built by hundreds of hands hundreds of times. By the time the mouth closes, they belong to the Vault in turn.
You are mine, says the Vault. It doesn’t need to provide further clarification.
