Saint Celestine was a Sister Repentia at the Order of Our Martyred Lady. It is said that she fell during a battle in the planet Eurytion after slaying over a hundred heretics. Her body was retrieved by her sisters and they found some signs of life in her.
By the morning she was well again and lead the battle to capture the capital city. It was over in just hours and she went on to become the figurehead of the Palatine Crusade before being caught in the atomic blast in Forrax.
