The Master-Brain Beneath the City

Beneath the streets there is no sound, only whispering in a tongue that is not yours. The sewers lead to a cavern where the walls breathe and think, warm and damp as the inside of a skull. Night after night the mind-reavers, pale figures with tentacles where a mouth should be, creep through the cellars of the city to harvest the dreams of the sleepers.

The people above scarcely notice: first they forget a name, then a face, then their own children. Every morning someone fails to wake. The reavers carry their plunder down into the depths, for at the heart of the colony something floats that hungers for more than they could ever bring, and it grows with every stolen dream.

You push into the veins of the colony, cut paralyzed victims free from the brood chambers, ward off the psychic assaults that would erase your own memories, and search for the nerve-cord that binds the colony to the whole sleeping city. Along the way you discover what ancient betrayal once drove the reavers into this darkness.

At the heart of the cavern waits the Mastermind: an aberration as large as a house, floating in a pool of cerebral fluid, thinking with the stolen dreams of half a city and speaking with a thousand pilfered voices at once. It turns your own thoughts against you. Will you break the Mastermind's grip and crush the colony before daybreak, or will your minds be the last dream it harvests?
