“Allowing you to plant the seeds of rebellion and play havoc with the lives of my people is a failure for which I must answer. But I will see Crimea through this trial. I will give my people the future they deserve, no matter the cost.”
Elincia was raised at birth in confidentiality, knowing issues may arise if her existence was known, so therefore she knows little of the outside world. But she would spend her life protecting her milk siblings.
After being deemed the new Queen of Crimea, Elincia tries to reinstate the crippled Crimea due to Daein's previous invasion and succeeds.
However, with Daein’s sovereignty restored, and Elincia’s decision not to press them for reparations to promote harmony, more people began to feel she was being too kind to their nation’s hated enemy. Thus, a lot of like-minded individuals who felt Daein was still their enemy formed a rebel faction to go against Queen Elincia, whereupon they proceed to formulate plans to usurp the throne from her. This thus leads to the arising of heated conflict between the nobility and Elincia’s most trusted retainers.
The political instability of the country is exacerbated by the capture of Lucia by Ludveck, who uses her life as bait to force Elincia into handing the rulership of the country over to him. Elincia is unexpectedly aided by the Greil Mercenaries once again, who assist in overturning the unrest in Crimea, saving Lucia in the process. Shortly after this, she speaks with Ike and thanks him for saving Lucia. When Ike asks if she needs Greil Mercenaries to help finish off the rebel army, Elinicia tells him that the royal knights will be able to handle it. Before Ike leaves, Elincia tells him about what has been going on in Daein, including the return of the Black Knight, who had been fighting alongside the Daein Liberation Army.
Sometime later, after the Laguz Alliance returns to Gallia after having been forced to flee Begnion, Senator Valtome, the new leader of the Begnion Central Army, decides to go through Crimea in order reach Gallia. When Elincia refuses to allow the army to pass through, Valtome orders his men to storm through the country and ransack the villages as they go. After learning of this, Elincia sends the Crimean Royal Knights to stop them. Afterwards, Elincia meets with Valtome, who accuses her of treason against Begnion and threatens to have her executed for her actions if she continues to interfere. She is then forced to allow the Begnion Central Army to pass through Crimea towards Gallia and that they are to be allowed to engage the Gallian army in towns near the border.
After Ashera awakens and casts her judgement on the world, Elincia, along with Lucia, heads towards the Tower of Guidance as part of the Hawk Army, lead by Tibarn. During their journey, she and the Hawk Army fight and defeat Valtome, who, along with the other senators, had been revived by Ashera to lead the Disciples of Order. Some time later, she reunites with Geoffrey, Bastian, and Volke, who had been spared from Ashera's judgement, and helps them defeat Izuka. After the battle, she reunites with her uncle, Renning, who she learns had survived the attack on Crimea three years earlier and been brainwashed by Izuka into becoming General Bertram of Daein. After Reyson heals him with the Galdr of Rebirth, Renning decides to fight alongside Elincia.
After the final battle against Ashera, Elincia will return to Crimea, where she is reputed to lead her nation into a golden age of peace and prosperity. She will be wed to Geoffrey if they share an A rank support at the end of the game.
"The queen of Crimea, a kingdom ruled by the wise beorc race. With deep pride and consideration for her people, Elincia rules justly, having taken the crown three years prior after winning the war against Daein. However, there are rumblings of discontent among Crimean nobles that threaten her kingdom. Elincia wields the mighty sword Amiti, passed down by Crimean royalty."
"Elincia ascended to the Crimean throne after her parents were murdered by the Daein army. Her efforts to restore the kingdom and aid her people led some of the nobility to plot against her, but the support she was given helped her usher in a new age of peace and prosperity."
