"While making repairs to SRA units in Sector 3382 on ██/██/████.2, Technician [DATA EXPUNGED] reported the discovery of human remains in an advanced state of decay. Analysis of clothing fragments discovered with the remains indicates the remains are 450-700 yrs old. Valid Foundation security credentials for Dr. Alto Clef were discovered nearby, although a genetic match could not be established. The following note was recovered from a hermetically sealed plastic document sleeve. Why did we have to build this thing? When did we do it? How long have we been doing it? Do we even know?! Subsequent interrogation has verified that Dr. Clef has no knowledge of this event, and is ignorant as to the purpose of the message."
