Tigan central computer

The central computer, exterior and interior views

The central computer was the store of all knowledge on the planet Tigan.

The central computer updated the Tigan population with new information by sending new data via minute tachyon pulses to interfaces which delivered the new information directly into the Tigans cerebral cortexes. However, when Tigan's planetary energy production facility, the gravimatrix, was being tested, a gravimetric pulse was generated which wiped the entire core. While the data was being re-input from written records, the government took the opportunity to make a few alterations, thus starting a conspiracy which lasted for centuries. At first revisions to Tigan's history were infrequent, occurring only ten times in the two centuries prior to 2364, but gradually it occurred more so, six in the decade prior to the same date. Evidence was erased that Tigan even had written records and the changes went so far as to remove entire political regimes from history.

The practice was eventually brought to an end in 2364 when Edic, one of the conspirators, realised the wrong that was being done and arrested his fellow conspirators. (TNG comic: "History Lesson")
