Oblivion Room. Named as such because of how the rooms appears once walking into it. This is just one of the harder to find rooms in the TARDIS. Very low light except for the specks that resemble fireflies or stars, the room is full of mirrors, like one dark mirror maze. It is named oblivion because it feels like it stretches on forever with nothing but darkness, false stars, long halls and dead ends. It’s not to hard to find your way out, since each ends of the room has an exit, it’s just a bit different once you’re in there. Some being completely unnerved by the silence and darkness.
And some finding piece.
Just don’t play hide ‘n’ seek in here, the Doctor knows all the best spots and can play a mean game of it.
