25FY The Mechanon menace on Volturnus first comes to the UPF's attention, but cannot be dealt with because of the Blue Plague (note the Blue Plague has been raging since 17 FY and will continue to do so for another 2 years by the book)

54 FY The Mechanon Revolt. Mechanons on Volturnus revolt. Only through quick action of the part of Star Law is a full-scale war avoided.

70 FY The Mechanon Civization of Voltrunus undergoes an upheaval. The majority of peaceful Mechanons migrate into undeveloped space between Scree Fron and Dixon's Star.

77 FY Mechanon is discovered by migrating Mechanons. Its entry into the UPF is blocked until the legal status of the Mechanons can be established.

105 FY (post SW2) An altered Mechanon assassinates the governor of Zebulon. The UPF suspects that the sathar may be establishing an extensive spy and terrorist network. The possible sathar use of mechanical life forms, such as mechanons, as agents becomes a preime investigative goal of Star Law.

106 FY The Mechanons are officially informed by the UPF that they are not considered a stable enough society, at this time, to be allowed equal status in the UPF. They are forthwith considered "wards of the Federation." The protection and supervision are the responsibility of the Council of Worlds. While most Mechanons accept this as a necessary step toward independence, some rebel and go underground, swearing to avenge their race. Many of these are suspected of being sathar agents.
