Lachesis

Lachesis ​is a playable character from Fire Emblem: Genealogy of the Holy War. She is the princess of Nordion and the younger half-sister of Eldigan. She adores her brother to the point that she believes that she will never marry due to knowing a man like him. If she is paired up, her children will be her son Diarmuid and her daughter Nanna.

Profile
Lachesis is first seen when Eldigan and the Cross Knights depart from Nordion Castle to fight against the Heirhein army led by Elliot in Chapter 1. She later appears in Chapter 2 when she attempts to stop Eldigan from negotiating with King Chagall in order to prevent a war between Agustria and Grannvale from occurring. Lachesis mentions that Chagall murdered his own father and therefore would not listen to anyone, but Eldigan ignores her concerns and departs for Agusty. When she learns that Eldigan has been imprisoned in Agusty for angering Chagall, she also discovers that Elliot is taking advantage of the situation to invade Nordion under orders from his father. She decides to defend Nordion Castle along with Eve, Alva, and Eva, the three knights whom Eldigan left behind to protect her. Around this time, she requests aid from Sigurd, who is stationed in a castle within Verdane that is close to its border with Agustria.

Once Sigurd comes to her aid, Lachesis asks him to rescue Eldigan, and joins his army. If her three guardian knights survive until the end of the chapter, she receives the Knight Ring from them before they return to Nordion. During Chapter 3, she can convince Eldigan to stop fighting Sigurd and instead try to convince Chagall to end the war as soon as possible. However, this ultimately results in Eldigan being decapitated by the king, leading Lachesis to declare that she will never forgive Chagall.

Lachesis survives the Battle of Belhalla and thereafter brings Nanna to Leonster to live with Finn, while Diarmuid is sent to stay with the other initial members of the Liberation Army in Isaach. She becomes a surrogate mother of sorts for Leif during this time, and seems to become acquainted with Selfina. Eventually, Lachesis decides to reunite with Diarmuid and begins a journey across the Yied Desert, during which she mysteriously vanishes without a trace. Although her fate is never revealed, it is suggested from a scrapped idea originating from Fire Emblem: Thracia 776 that she may have been captured by the Loptyrian Cult and turned to stone. While Diarmuid reveals in both of games that he learned from Lewyn that she disappeared, he states in Thracia 776 that she may still be alive somewhere with her whereabouts unknown.
