The Starfleet fleet admiral who informs Captain Picard in 2368 that Ambassador Spock has been seen on Romulus and sends the Enterprise-D to find out why.
Fleet Admiral Brackett appears in the opening scene of Unification I in the fifth season. She summons Picard to a starbase and shows him a long-range intelligence image taken on Romulus two days earlier. The figure in it is Spock, who has left no word of his plans with anyone.
Starfleet has to consider the possibility of a defection, which she describes as potentially the most damaging in the Federation's history, given what Spock knows. She asks Picard to speak to Sarek, who is close to death on Vulcan, and then to learn the truth by whatever means he can.
Her orders set in motion the secret journey of Picard and Data to Romulus aboard a Klingon ship. She was played by Karen Hensel.
