Bone spider

From Tardis Wiki, the free Doctor Who reference

Bone Spiders were sentient creatures that fed off dreams. They could force an individual to live out their greatest nightmares, by making them come to life. They would then trap their victims in strong strands of webbing, which could also preserves the victim's form and make them invisible to others. They could also create stone version of other beings, which would collapse upon being touched by a living being. (PROSE: The Stone House)

hISTORY

In 2016 a female spider and her baby fell through a tear in space-time, and ended up in an old stone house. The female then lured a young teenager, Amira to the house where she fed off her by making her re-live the memory of her younger sister Yana choking to death. Amira became trapped in the spider's webbing, which made her invisible to others. She could break out of the webbing if she wished, but any attempts to leave the house and the spiders would created more webbing to trap her. Yana would appear to Amira sometimes, usually in a spectral form as she re-lived past memories. Over the years, the spiders changed Yana's form to suit that of what many urban legends stated which was that the house was haunted by a faceless ghost. Eventually Yana would appear to both Amira and outsiders as a ghost with no face. Amira reached out to Tanya Adeola and she felt drawn to the house too, in the same way that Amira was. Tanya investigated with the rest of the Coal Hill defenders, and the spiders tried to trap her too but were brought to an end resulting in Amira's rescue (PROSE: The Stone House)
