Overcaste
From Tardis Wiki, the free Doctor Who reference
The Overcast, or Overcaste were type-epsilom primitives from the planet Golgauth. They shared a collective consciousness, one which caused a psychic tether to form with the Cyclors, a race from another dimension. (COMIC: The Organ Grinder) For twelve hundred years their race prospered due to the help of the Cyclors, who raised them from savages. During the Last Great Time War the War Doctor meddled with time, turning the Cyclors into the Malignant, who wiped out over fifty generations of the race. Nine-hundred years later, after the Time War had ended, they held the Eleventh Doctor responsible for the creation of the Malignant on their Palliative Ark. (COMIC: The Then and the Now)
