Entity 140 (Lady Blanche Von Haderach)

Entity 140, or Blanche, as she prefers to be referred to as, is a humanoid figure that presents herself as a pale woman with long blond hair and light blue eyes. Despite presenting as female, Blanche has no gender, and has additionally stated to be aromantic and asexual. She has predominantly been seen wearing multiple white dresses, various pieces of jewelry (most notably a sapphire pendant she seems to keep on her at all times) and, occasionally, opera gloves, glasses and various types of hats, though many other outfits have been reported. Her body has been reported to bend, stretch, or deform in ways not humanly possible, though such reports are very rare. It remains unknown if these odd movements occur due to anomalies in Level 906’s nature or Blanche herself. Blanche has shown a vast suite of anomalous abilities. While the full extent of them is still unknown, she is known to be able to read minds, communicate telepathically, move, create, destroy, or summon objects with a mere thought, change her appearance, alter the flow of time in her library, teleport, and to be aware of everything inside the Cygnus Archive, though this is yet to be confirmed. In short, we have reason to believe that Blanche's abilities, while confined to The Backrooms Level 906, are as close to omnipotence as it gets, giving her complete control over the Cygnus Archive and everything within it.
