Dwellers of Darkness

The Dwellers of Darkness were a formless entity/collective that were able to kill their victims and use their memories to create physical projections to terrorise the living.

History
The origins of the Dwellers is unknown, but it is suggested they have been around almost as long as the universe. They became so legendary that they were used as part of ghost stories on various planets, particularly Gallifrey.

They took refuge in a suburb in the 1970s, killing a little girl called Louise and using her memories to terrorise Daniel, the brother. They drew the Doctor and Jess' TARDIS off course in order to suck the energy from a time traveller. The Doctor was able to identify them, but not before the Dwellers took them to the End, a void dimension where the last remnants of their victims were sent. They were eventually defeated when Daniel was able to use his want to see his parents once more to bring the house back to the right place. They can't be killed, so it is presumed they went to another person.

Physical Appearance
The Dwellers are technically formless, so do not bear a physical appearance.

Powers and Abilities
They live in the darkest areas of the universe, lurking in the shadows. Any victim who goes near these shadowed areas is consumed, and their memories drained. These memories can then be used to create physical projections that attack the living, distracting them long enough for the Dwellers to sen them to the End, a void where they can completely drain their victims. The capacity to create the physical projections is helped by the presence of a living being that shares the memories of the victim. If the living person dies, the link is broken. The only other way in which the link can be broken is if the living person has a desire that keeps them tied to their own world.
