She was from an unknown race of aliens, and she appeared to be ideally suited to playing the piano: she had two pairs of hands. She enjoyed suck salt, though she considered it a nasty habit. She offered to play Andorian blues for Commander William T. Riker. Instead of paying her money for information, Riker taught her some jazz routines on the piano. She also played a selection from the Klingon opera Aktuh and Maylota for Worf.
Amarie's ex-husband, an arms smuggler, was killed when his warship encountered the Enterprise-D in 2368. Riker contacted her when he was investigating the incident and the theft of surplus Vulcan ships and materials. She directed him to Omag, a Ferengi arms trader, whom she said always wanted to hear the same song, "Melor Famagal". (TNG: "Unification II")
Amarie was played by actress Harriet Leider. Cindy White worked as photo double for her during the close ups of her hands and pianist Jerry Zimmer performed the piano music and the second pair of hands seen in the episode.
Her species may be the same race as the unseen Terellians, who were also known to have four arms.
