Tay Vanis was an Alliance Intelligence agent who operated during the Galactic Civil War under the codename Tiree. Based aboard the modified freighter Home under General Lens Reekeene in the early stages of the war, Vanis sparred with the Imperial Security Bureau agent Mar Barezz, who repeatedly attempted to capture the elusive "Tiree." Though he had already participated in the maximum number of missions before mandatory retirement, Vanis continued to serve the Alliance, albeit "off the record." He was instrumental in the recruitment of many future members of the Alliance around the time of the Battle of Yavin.
