Nerrine is the second leader of the Martian colonists who came to Earth 250 million years ago. She was the wife of Garaka, the first leader of the colonists, and inherited the rights of leadership upon Garaka's death. Better known for her stunning beauty than her warrior spirit, there were whispers that her rank and prestige as a warrior were secured for her by her mate. Those whispers that now fill her with doubts about both her ability to lead and her right to do so-- doubts Ress seems keen on exploiting.

The name Nerrine, chosen for her by Garaka, means both "wife" and "an restful interlude between battles".

At the time they crash-landed on Earth, Nerrine was 13 in Martian years (biologically, around 25 or 26 in Earth years).
