Deviation O-028 is the projection of an extra-dimensional entity within three-dimensional space. It seems to be composed of a material somewhere between metal and obsidian, and each of its faces comprises a countless number of triangular facets. O-028's form changes frequently, albeit at irregular intervals. It most commonly presents as a square pyramid split into four layers whose base-to-height and height-to-hypotenuse ratios are each 1:1.27. The primary Deviation Trait displayed by O-028 is extra-dimensional contamination. Any organism that comes into physical contact with O-028 will temporarily gain extra-dimensional properties, such as becoming the projection of a higher or lower-dimensional entity or acquiring entirely new senses. Appendix O-028-001: Partial list of effects of exposure to O-028 · O-028 form: Four-layered square pyramid Result: Subject gained four-dimensional awareness. Duration: About 250 milliseconds. · O-028 form: Flat geometrical shape resembling a Sierpiński carpet. Result: Subject was curled up in multiple dimensions, thus becoming invisible in three-dimensional space. Duration: About 120 minutes. · O-028 form: Flat geometrical shape resembling a snowflake. Result: Subject acquired a powerful sixth sense toward threat or hostility, causing them to receive a mental warning when danger or harm is imminent. Duration: About 120 minutes. · O-028 form: Two three-dimensional square pyramids connected at their apices to form an hourglass shape Result: When multiple subjects were exposed, they experienced a mental link that allowed them to communicate in a manner similar to telepathy. Duration: Permanent Appendix O-028-002: [Permission Denied] Appendix O-028-003: [Permission Denied] Appendix O-028-004: [Permission Denied] Securement Procedures: DO: Secure O-028 in Grade VI or higher S-Vessel for valuable objects. DO NOT: Interact with O-028 when it manifests any of the forms described in Appendices O-028-001 to 004.
