During the Klingon Civil War in early 2368, Fleet Admiral Shanthi met with Captain Jean-Luc Picard to discuss his plan to blockade the Klingon-Romulan border using a task force to establish a tachyon detection grid. Following approval from the Federation Council, Shanthi authorized Picard's plan, which would lead to the downfall of the House of Duras. (TNG: "Redemption II")
In 2370, Shanthi was posted at Starbase 247. She was contacted by Captain Picard after the incident involving the USS Pegasus and an illegal Federation phasing cloaking device. She assured Picard that the leading figure in the incident, Admiral Erik Pressman and several other officers at Starfleet Intelligence would face a full inquiry and probably a general court martial. (TNG: "The Pegasus")
Shanthi was played by actress Fran Bennett.
The script for "Redemption II" identifies her as being the head of Starfleet, and Picard's captain's log entry at the beginning of the episode refers to her as fleet admiral, despite an apparent costume error in which Shanthi wears the rank pips of a vice admiral. Shanthi is again referred to as fleet admiral by Picard in "The Pegasus".
According to the call sheet for Monday 16 September 1991, Bennett was up to reprise her role as Shanthi for the fifth season episode "Unification I" but was replaced by Karen Hensel as Admiral Brackett.
The first draft script of Unification I calls her "Shanti".
The novel Articles of the Federation gives her the first name Taela and reveals that she retired from Starfleet sometime before 2380.
