Anij was a Ba'ku female who was over three hundred years old, although she only appeared to be in her late 30s/early 40s.
Anij and Captain Jean-Luc Picard openly expressed a mutual interest in each other. During her time with Picard, Anij demonstrated the ability to slow down time for both of them when engaged together in a moment of deep, personal connection.
While escaping from the Son'a, Anij and Picard became trapped under rock debris due to a cave-in and Anij was critically injured. While holding Picard's hand, Anij managed to slow down time around them long enough for the rest of the Enterprise crew to reach them.
