Cassandra "Catherine" Rubens Charon

A member of the Knights of Seiros and wielder of the Hero's Relic Thunderbrand. She deeply reveres Archbishop Rhea. Appears in Fire Emblem: Three Houses. Name: Cassandra "Catherine" Rubens Charon Gender: Female Race: Human Birthday: September 15 Age: 27 Height: 175 cm Relatives: Charon (Ancestor), Count Charon (Father), Unnamed Brothers and Sisters Occupation: Teacher at the Officers Academy, One of the Holy Knights of Seiros Weapon: Thunderbrand </Personal Information> Catherine appears as a tall dark skinned woman with blonde hair tied into a ponytail and blue eyes. Her attire consists of a white slit dress that exposes her left leg area, a silver chestplate over the dress, silver armplates, black gloves, white trousers and black boots with shin guards on them.

As one of the most powerful Knights of Seiros, Catherine is extremely loyal and a devout believer in the Church and Rhea, the latter being an attachment. This is due to Rhea taking her in during her greatest time of need, and as such, feels that it must be repaid in full. Her devotion to the Church is so extreme that in a conversation with Shamir, if someone spoke of heresy and she didn't know them, she'd cut them down on the spot. Her loyalty to Rhea is also unwavering; she would save her over anyone else, and follow her to the very end despite the apparent insanity she falls into during Crimson Flower. Aside from her role as Rhea's bodyguard, Catherine is a fierce warrior with a reputation to back up her skills, being known as Thunder Catherine. While many knights idolize her, she feels that she is not worthy of such praise. She gets along well with fellow knights Alois and Shamir, especially with the latter despite their vastly different personalities, due to having fought many battles together. If the support is pursued, Catherine ultimately worries for Shamir's well-being alongside Rhea's, and admits as much to her. She is also willing to help others, such as telling Ingrid to resort to dirty tactics as a last resort, as war can be quite dirty and not what the stories make it out to be. She also helps Ashe find closure in the role she played in Christophe and Lonato's deaths. Despite being a member of House Charon, one of Faerghus' most noble and prominent houses, Catherine dislikes her noble title, as she feels that it keeps her chained to a life she doesn't want to live. In her ending with Lorenz should Rhea be killed, it states that she preferred relaxing in a tavern rather than dressing up for court. She has an innate sense of identifying people with crests with a single glance. She could correctly pick up on Lysithea's crest secret and knows that she has a Crest of Charon like she does. The two can form a bond akin to sisters if their support is pursued. She has the moniker of "Thunder Catherine".

Catherine is a character from Fire Emblem: Three Houses and Fire Emblem Warriors: Three Hopes. She is a Knight of Seiros, and she can train Byleth in Swords and Brawling. She possesses a Major Crest of Charon. Catherine is an alumnus of the Garreg Mach Monastery Officers Academy. She is a fearsome swordswoman who wields Thunderbrand, one of the legendary weapons known as the Heroes' Relics, and is completely loyal to Archbishop Rhea. Catherine claims to be able to identify a person's Crest just by looking at them. Catherine was born to House Charon in the Holy Kingdom of Faerghus under the name Cassandra. She attended the Officers Academy in the Blue Lions House, alongside her best friend Christophe. One day, she and her classmates were tasked with killing monsters, but they were ambushed and she nearly died. Rhea saved her and nursed her back to health. Some time after graduating, she was implicated in a plot to kill the king and had to flee the kingdom, becoming an outlaw. She sought safety at Garreg Mach Monastery and Rhea took her in, making Cassandra her knight. Cassandra then changed her name to Catherine. During this period, she also was responsible for capturing Christophe and turning him over to the Knights of Seiros for execution, which cleared her of any wrongdoing. However, in response, Christophe's father Lonato pinned a baseless crime on her, making it impossible for her to ever return to Faerghus. The incident would haunt her for the rest of her life. When Shamir joined the Knights to repay a debt for Rhea, Catherine took the time to introduce herself to her. When Shamir simply introduced herself to her in turn, Catherine was surprised by her response and believed that she would be hard to get along with. This changed during battle, when the two saw each other's strengths and decided they worked best as a team. She uses a sword named Thunderbrand, which is one of the legendary weapons known as Heroes' Relics. She also has an innate sense of identifying people with crests with a single glance.
