Warhammer 40k - Adepta Sororitas - Shards of Celestine

The Adepta Sororitas, colloquially called the "Sisterhood," whose military arm is also known as the Sisters of Battle and formerly as the Daughters of the Emperor, are an all-female division of the Imperium of Man's state church known as the Ecclesiarchy or, more formally, as the Adeptus Ministorum.

During Celestine's resurrection trials she must pass every time she dies, she encounters two shards of her soul: "Faith" and "Duty" who remain separate, but support her like the Geminae. Upon completion of her trials, they return to life with her, instead of merging with her. This heavily implies that when she chooses two Battle Sisters as her new Geminae Superia, they are imbued with these soul shards to empower them and turns them into duplicates of her previous Geminae Superia
