Ursula

Ursula ​is one of the Four Fangs, an enemy character in Fire Emblem: The Blazing Blade sent out to kill Eliwood, and is later resurrected as a morph by Nergal.

Profile
Ursula is unique amongst the Four Fangs, as she is the only one who specializes in magic. She is known as the Blue Crow amongst the Black Fang members. She shows complete devotion to Brendan Reed's new wife, Sonia, and seems to be aware of the fact that Sonia is a subordinate to Nergal.

Ursula is first seen in Chapter 7x of Lyn's story, where she assigns a Black Fang operative, Beyard, to recapture the children, Ninian and Nils, for reasons unknown at the time. She is not seen again until the chapter Kinship's Bond, where the Four Fangs are assigned to kill the lords Eliwood, Hector, and Lyndis. The Four Fangs were deceived by Sonia that the three lords were corrupt nobles who had to be stopped. Later, Ursula is seen in another chapter, handing the tactician a Hammerne staff because, despite her orders to kill the lords, she did not want Vaida to succeed in doing so.

Ursula is seen for a fourth time in the chapter Battle Before Dawn, where she witnesses Jaffar attempting to escape after abandoning his assignment to kill Prince Zephiel for King Desmond, and Nino for Sonia. Ursula then takes it upon herself to execute the law of the Fang and kill the two traitors, in addition to completing the assassination of Zephiel. Eliwood, Hector, and Lyn arrive at the same time, and Ursula battles both groups. Ursula ultimately fails, either dying in the battle or, if she survives the battle, is killed by Limstella for failing in her duties. Her quintessence is harvested by Limstella for Nergal either way.

She is seen one last time in Final Chapter: Light, as a morph created by Nergal's magic. She wields the powerful tome Excalibur, which the player receives upon her defeat.
