The holographic custodian of the quantum archive in San Francisco, who admits Picard to his stored belongings in 2399 and identifies Data's painting titled Daughter.
Index is a hologram that looks after the secure quantum archive attached to Starfleet's archive museum in San Francisco. She appears in Remembrance, the first episode of Picard, played by Maya Eshet.
After Dahj comes to him for help, Picard visits the archive, where the keepsakes of his career are held in stasis, among them a Captain Picard Day banner, ship models and a Klingon bat'leth. Index greets him courteously and retrieves a canvas he has not looked at for years.
She tells him that it was painted by Commander Data in 2369, that it is one of a pair whose twin hangs in Picard's home, and that its title is Daughter. The woman in the picture has Dahj's face, which sets Picard on the trail of Data's descendants.
