The Chancellor of Tigan was the title of the political leader of the Tigan people of the planet Tigan. For centuries the political makeup of Tigan has been in flux due to the society altering effects of Tigan politicians rewriting Tigan history via the Tigan interface, a device every member of the society is implanted with which informs them of the latest updates to the Tigan central computer, the store of all Tigan history. In the year 2364 Chancellor Lomac was knocked from power via this mingling, how many other chancellors might have been replaced by these means is unclear.
