Square D SCP521

SCP-521, also known as "Square D," is an anomalous entity that takes the form of a rectangular piece of paper measuring 20 cm by 20 cm. The entity is made up of unknown material, as all attempts to alter or damage it have proven unsuccessful. SCP-521 emits a faint, bluish glow at all times, but the source of this illumination remains unknown.

When a human or animal comes into contact with SCP-521, the entity affects their mental and physical state, inducing a trance-like state. Subjects become completely unresponsive to external stimuli and display a heightened suggestibility, effectively making them highly susceptible to commands and suggestions. This effect varies in intensity depending on the individual, with some subjects being more easily influenced than others.

During this trance state, SCP-521 "projects" detailed, three-dimensional holographic images directly into the minds of affected individuals. These images are often complex and vivid, depicting scenes of various landscapes, people, or objects. The exact nature and purpose of these images are currently unknown, as no consistent patterns or themes have been identified.

The effects of SCP-521 slowly wear off over time, with subjects gradually regaining their normal mental and physical faculties.
