T'Sari was a female Vulcan scholar-artist who lived in the 4th century on planet Vulcan, or T'Khasi as it was commonly known then.
T'Sari combined astronomy and art to create a stylised map of her homeworld and its place in the Nevasa trinary star system. She was believed to have created it during the period of mourning following Surak's death, hence the map's name: "T'Khasi (Vulcan) at Surak's Passing".
