San was a female Human, and a spiritual outcast from the Jidaigeki clan. Following the Klingon War and the Secret Wars that proceeded, San became Spock’s apprentice. She became a Commander in the United Federation of Planets. She eventually decided to leave the Jidaigeki in search of her own path. Shortly after, the Dark Lord, Baron began to hunt the remaining members of the clan.
After the rise of Baron and the Borg Collective, San went into hiding and helped establish resistance against the Borgs. She went on rogue missions. She helped the United Federation of Planets fight against Baron, and after he was defeated, she became a wanderer. During the beginning of the Borg Collective War, San went on a journey across the Dark Corners of the Universe. (Star Trek: Journey to the Dark Corners)
