|Taken Name||Rosella Ember|
|Faction||The Irish Sanctuary, The Resistance|
Rosella Ember is an Irish Sanctuary operative.
In Death Bringer she was relatively new to the Sanctuary, and rather excited about raiding the Necromancy safe house and killing Melancholia, along with Rosella Ember. Kallista is one of the Sanctuary Operatives who expresses their displeasure at the order to capture Melanchola St Clair alive, believing it safer and more satisfying to kill her.
Kallista is then teleported to the Necromancer safehouse with the other Sanctuary operatives. As no casualties are mentioned during the assault, it is assumed that she survives. It is unknown what happens to her after this.
In The Dying of the Light , it is revealed that a version of lived in the alternate dimension. After Serpine rescues Valkyrie from Nye and takes her to the new headquaters of The Resistance, he mentions having "made mistakes" after replacing China Sorrows as the leader. Rosella was one of the "mistakes" mentioned - implying that she was apart of The Resistance, and also killed by Serpine. (Flaring, Shakra, Ashione, Luciana, Kallista, and Rapture are also mentioned "mistakes".)
She is based on an Australian fan of the books.
