Thelianaresth "Thelian" th'Vorothishria was an Andorian thaan who served as an officer in the Federation Starfleet before going on to become one of the most influential Presidents of the United Federation of Planets of the 24th century.

Thelian was the Federation President when first contact was made with the Cardassian Union. (TTN novel: Taking Wing) Thelian attended a historic meeting with the Legarans at Vulcan in 2327, to which the Cardassians had been invited as observers. However, Cardassian efforts to sabotage the talks and assassinate the Legaran delegation, though disavowed by the Cardassian government, served to damage diplomatic processes, leading eventually to the Cardassian Wars. (ST comic: "Enter the Wolves")

While in office, Thelian had a château built in the Loire Valley to serve as his home. Château Thelian, as it came to be known, became the official residence of the Federation President, used by and containing portraits of every president after Thelian.

By 2380, Thelian was the oldest surviving former president of the United Federation of Planets. Upon the death of Jaresh-Inyo of Grazer that year, he was one of only two living former presidents, the other being Amitra. The elderly Thelian's poor health prevented him from attending Jaresh-Inyo's state funeral on Mars. (ST novel: Articles of the Federation)

The dating of Enter the Wolves established Thelian served at least one term in office from 2325 to 2328; other dates given in the succession box below are conjectural.
President Thelian is depicted in Enter the Wolves wearing a Starfleet uniform, even though he would have had to leave Starfleet in order to run for office (as per Articles). One possibility is that he wore his uniform on formal occasions in lieu of Andorian formal dress, as is his right as a former officer.
In The Return, Hikaru Sulu becomes president around the general time period of Thelian's leaving office.

Alternate timelineEdit

In an alternate timeline, Thelian served as the Field Marshal of the Interstellar Guard (a position analogous to the Commander-in-Chief of the Federation Starfleet) in the 2290s. (ST - Myriad Universes novel: The Tears of Eridanus)
