the construct is the enigmatic final creation of the equally mysterious Fleeting Cacophonies Amidst a Motionless Chasm. built from the old shell of an abandoned dyson sphere, its exact function, nature, and purpose remains unknown -- its creation was a matter of near-total secrecy, and virtually all of of Fleeting's notes pertaining to the construct were destroyed in the same fire that killed Him, with the surviving documents only warning not to breach, enter, or even so much as peer into it for any reason, in a manner as if to suggest that it possesses some manner of cognitohazardous properties, and vaguely alluding to its purpose as being a device that would somehow "end death".
unusually, when asked about Her brother's creation, Solitary Lights Amidst a Motionless Chasm noted that Fleeting had never so much as alluded to His work on the construct, and had seemingly been entirely unaware of its existence, further lending credence to the idea that the construct is somehow cognitohazardous in some capacity.
