“A woman who walks with a storm in her veins.” - Lysander au Lune
As a child Seraphina was described as a pale-faced, gaunt girl with messy short-cropped hair.
10 years later, Seraphina is described as a fierce looking woman who is not as beautiful to Luna’s standards because of the hint of wildness beneath her surface. She has full lips, a slightly hooked nose, and her eyes are a dull-gold. Compounding her natural ferocity, she wears her hair buzzed short on one side of her head.
Seraphina grew up on Jupiter’s moon Io in the Raa family home set in the shadow of a volcano in a large yellow plain. The home and the small property surrounding it was enclosed by a pulse bubble to protect it from the elements of Io’s surface. The home was a collection of various gardens connected to smooth, white-walled rooms with no roofs. The architecture, very minimalistic and accentuated the landscaping and greenery.
Like her siblings, Seraphina was raised without access to the HoloNet until the age of 12 so that they could form their own opinions on their studies before they hear the opinions conveyed by media. She was privately tutored and had no servants. All evidence suggests her childhood was peaceful yet disciplined. She had chores, such as gardening, and was raised by a family who taught her life-lessons through many facets whenever possible. She was a wise, thoughtful, and confident. So inquisitive that she would climb the ivy on the outside of her family home to listen in on the adult-conversations she was closed off from. Her only involvement in Morning Star is a brief conversation with Darrow, when he travels to Io to visit her father, Romulus au Raa.
Seraphina is found by Lysander when he and Cassius board the Vindabona. Seraphina has been trapped in a wire tacNet, where she is mostly naked and covered in engine oil. Lysander chooses to rescue her first. She demands his stims, and he gives her the last of what he has. She takes his razor to exact her revenge on the Ascomanni, leaving Lysander unable to help the remaining lowColor crew members. She returns in even worse shape, but Lysander gets her on the Archimedes, and the ship continues her course to the asteroid, S-1392, that she had paid for passage to, while she is in and out of consciousness. Lysander continues to try to care for her wounds. After the Archi is intercepted by a Rim warship, she is discovered in the medbay of the Archi while Cassisus and Lysander are being interrogated. She tells Diomedes she has found nothing and insults Pandora, who insists she must have found something. After the return trip, Seraphina is in full health. She is brought to her father, Romulus au Raa in a remote outpost. She calls Cassius and Lysander friends for saving her life. She argues with her father about where she has been and why. She argues with Marius, her brother and her father's Quaestor, about the use of torture and killing of an Obsidian, Hjornir. Seraphina reveals she was looking for the truth of what happened to the Ganymeade Docks. Her father reveals he has no intention of letting her return to Sungrave, but instead he plans to keep her out of sight, virtually under house arrest for the rest of her life as punishment for leaving. She is dragged out of the room.  After Dido's arrival and subsequent clash with Romulus, Seraphina is released, and tells her mother she has found what she was looking for on her trip. She tells Dido Cassius and Lysander saved her life, and Dido calls them guests. 
Her mother is Dido au Raa.
Her father is Romulus au Raa.
