T'Leikha was a female Romulan who served the Romulan Star Empire in the 22nd century.
Her position as First Consul went as far back as the year 2155 when she used her influence to free Admiral Valdore from his imprisonment in order to spearhead a new offensive against the Coalition of Planets. (ENT novel: The Good That Men Do)
In 2156, T'Leikha and Valdore conspired together to kill Praetor D'deridex. Later, T'Leikha conspired with Nijil to kill Valdore, but this attempt was unsuccesful. (ENT novel: Beneath the Raptor's Wing)
After the Earth-Romulan War she confronted Valdore in his office, furious over the treaty that ended the war and established the Romulan Neutral Zone. During this meeting she assassinated Admiral Valdore and was in turn killed by his aide Terix Val'Danadex Trel tr'Llweii. (ENT novel: To Brave the Storm)
