Soval was a Vulcan male in the 22nd century who served as Vulcan Ambassador to United Earth from United Earth's formation before becoming Vulcan Foreign Minister in 2155. Soval was a controversial figure who began his career favoring restricting Humanity's attempts to explore space until they were "ready;" in later years, however, he became an advocate of Earth in the Vulcan government. Soval had a great deal of influence on the development of the Coalition of Planets and was one of the signatories of the Articles of the Federation.
