| NOTE: This page is only for Rhea/Seiros of the Empire routes in both games and the Golden Wildfire route in Three Hopes, in which she serves as a villain. |
| “ | So, this is the choice you have made. You are just another failure. Your presence soils this Holy Tomb and disgraces my brethren. I will not allow one who would lend our enemies strength to wield the power of the goddess Sothis! I have passed judgement! And now, I shall now rip your chest open, and TAKE BACK YOUR HEART MYSELF! | „ |
| ~ Rhea's villainous breakdown upon seeing Byleth side with Edelgard von Hresvelg. |
| “ | I have no patience for foolish questions. I shall sacrifice as many lives as it takes! That apostate who insists on taking everything from me WILL BE CRUSHED BY MY OWN HANDS! | „ |
| ~ Rhea/Seiros to Catherine regarding Byleth. |
| “ | NONSENSE! Fools who do not accept their own sins are undeserving of salvation! You humans are the ones who betrayed! You betrayed me, and you betrayed my mother! | „ |
| ~ The Immaculate One fighting Edelgard. |
| “ | So be it! I WILL CRUSH YOU WHERE YOU STAND! | „ |
| ~ Seiros to Edelgard in the Scarlet Blaze route/Claude in the Golden Wildfire route in Fire Emblem Warriors: Three Hopes. |
Seiros, also known as Archbishop Rhea and the Immaculate One, is the tritagonist within the Fódlan Saga of Nintendo's Fire Emblem franchise.
She is one of the two secondary antagonists (alongside the Flame Emperor) of the 2019 tactical video game Fire Emblem: Three Houses and one of the two main antagonists (alongside Thales) of its 2022 spin-off sequel Fire Emblem Warriors: Three Hopes.
She serves as the founding saint and Archbishop of the Church of Seiros, and is also revealed to be the daughter of Sothis. While she isn't exactly evil and does have good intentions, her actions still caused a lot of problems in the story, especially her false propaganda of Crests, which motivate the actions of Edelgard, Dimitri, and Claude to change the Crest system.
If the player decides to oppose Seiros, she will serve as the main antagonist of the Crimson Flower route in Three Houses, while in Three Hopes, she will serve as one of the two main antagonists (alongside Thales) of the Scarlet Blaze route, and the main antagonist of the Golden Wildfire route.
She is voiced by Kikuko Inoue in Japanese and Cherami Leigh in English.
Personality
Like most characters, Rhea's personality differs depending on the path Byleth chooses. When Byleth sides with her and the church, she does everything she could to help them, even turning into the Immaculate One to destroy the Imperial soldiers and monsters. In Silver Snow and Verdant Wind, during the Timeskip, after she was rescued by Byleth from the Empire, Rhea reveals to them the truth about everything, which included Byleth's identity, as well as hers. She also feels regret for the actions she has done, because while she admits that she was trying to keep peace of Fódlan, she was also driven by her selfish motives. She also feels sorry for treating Byleth as a tool to revive Sothis, which is how she abandoned her goal of using them, since she realized that Byleth is their own person.
In the Crimson Flower route, where Byleth chooses to side with Edelgard instead, the kindness Rhea showed towards Byleth completely vanishes, replaced with a ruthless and angry personality. She swears to kill Byleth and take back their Crest from their heart in an attempt to get Sothis back, as she deems that Byleth is a failure for a vessel. During the Timeskip, Rhea sends the Knights of Seiros to take back the Monastery, but hears from Catherine that they have failed. Depending on if Byleth chose to spare or kill Seteth and Flayn, Rhea stays angry, but in different ways. If Seteth and Flayn are spared, Rhea assures to herself that she is now the only Nabatean left to stop Byleth and the Adrestian Empire, and tells her mother to wait until she "frees" her from Byleth. If Seteth and Flayn are killed, Rhea expresses more anger at Byleth for not only "stealing" Sothis, but also killing Seteth and Flayn as well. Soon, in Tailtean Plains, Seiros discards her alias as Rhea and commands her knights to call her by her real name. After hearing that Dimitri has fallen as well, Seiros becomes more vengeful on killing Byleth, even believing that they are just the same as Nemesis. In the final chapter, her most villainous side is shown. She orders Catherine to set fire on Fhirdiad, despite that the civilians are still there. She is highly obsessed with killing Byleth, Edelgard, and the Adrestian Empire that she is even willing to sacrifice others, the fact that even Catherine is horrified by this action.

Trivia
- Seiros/Rhea is the only final boss of the game that is fought in two routes.
- Rhea is the only major (potential) supporter of Byleth that remains unplayable in all routes, even in the Silver Snow chapter/Church route. Through datamining, however, there are unused data for Rhea/Seiros that she was meant to be a playable and recruitable character during the production, like Sothis and Jeralt, but was eventually finalized as an NPC character. In Fire Emblem Warriors: Three Hopes, she, along with Sothis, became unlockable playable characters in New Game+, while Jeralt can be recruited and become playable if the player spares him.
- Azure Moon is the only path that Rhea does not play a major role in. However, Dimitri's war against Edelgard greatly mirrors Seiros' war against Nemesis many years prior.
- Etymology: Rhea is named after a Greek titan known as the "Mother of the Gods" due to being the mother of major Olympians including Zeus, Poseidon, Hades and Hera. The name may also refer to the mother of Romulus and Remus, the mythical founders of Rome.
- Seiros may be derived from Seirios, Greek for "scorching", and an alternate name for the star Sirius.
