As distant cousins of Manon, both Edda and Briar had the same silvery, moon-white hair but dyed it black after learning that white hair can stand out in the darkness. During Kingdom of Ash she washes the dye out to blend in better with the snow. Edda was youthful and beautiful in appearance. Unlike most Blackbeaks, her eyes were brown.
Like her cousin Briar, she rarely spoke, never laughed, and sometimes even Asterin herself couldn't detect her until she was at her throat. Both of the Shadows were raised in darkness and trained to blend into any sliver of darkness and listen. Edda and Briar's only show of humor was when they snuck up on coven members and frightened them for fun.
Some time before the series began, Edda joined The Thirteen.
After winning the War Games, Edda goes with Manon, the Thirteen, and half the Ironteeth witches to Morath to assist Duke Perrington. After four week in Morath, the Thirteen become suspicious of the strange goings-on and are grating against Duke Perrington's orders. As Manon's Shadows, Edda and Briar have reported whispers of stone alters stained with blood and dungeons blacker than the Darkness. On the duke's orders, Manon takes her Thirteen hunting for people living in areas near Morath.
The Thirteen take Kaltain Rompier, Duke Perrington, and his men to a tribe in the White Fang Mountains and Kaltain tortures them with her shadowfire. Duke Perrington then has the Thirteen slaughter the tribe.
The Thirteen are meeting when they’re interrupted by a man with a Valg inside him. He attacks them with darkness and mental pain. Manon kills him while the human trapped inside, Roland Havilliard, begs for death. Manon looks on in horror at the effect that the Valg powers have on those among the Thirteen without golden eyes. Because Edda doesn't have gold eyes, she is affected by the Valg powers and is on her hands and knees vomiting.
The Thirteen barely escape the explosion caused by Kaltain that destroys one-third of Morath, which includes the destruction of the evidence of the Thirteen’s actions. The Thirteen drop Elide Lochan off in the Oakwald Forest and send her on way before returning to Morath. The Thirteen decide to stay at Morath until the Matron arrives and then they will decide what to do.
Edda is with Manon and the Thirteen as they tensely greet the Blackbeak Matron and her coven at Morath. The Thirteen are sent on a mission to take control of Rifthold and bring Dorian Havilliard, now king, to Erawan if he survives. They are also ordered to destroy the glass wall Aelin Galathynius made surrounding the palace. Before leaving for Rifthold, Manon tells the Thirteen not to let anyone kill Dorian. Edda participates in the sacking of Rifthold. She then attends Manon's trial for the death of five Yellowlegs witches.
At Asterin's execution, she and the Thirteen give Manon the gesture to honor a Witch Queen. When Manon yells at the Thirteen to run, she helps the Thirteen escape on their wyverns. Edda and Briar stay behind to help Manon escape. When six Yellowlegs witches come after them, the three of them split up, drawing two Yellowlegs after her. She is able to get away from them and escape to safety.
The Thirteen arrive at the beach in Eyllwe and join in the battle against Maeve's armada. They help Rowan and the group win the battle. The Thirteen is reunited with Manon afterwards. Manon asks them if they heard the truth about her parentage and if they will still follow her. Asterin tells her that they will, and once again the Thirteen give her the gesture honoring a Witch Queen. Manon declares that they must become better than their foremothers. Manon, the Thirteen, and Dorian promise the group that they will find the third Wyrdkey and the Crochan witches to unite them to fight with Aelin.
For the past two months Manon, the Thirteen, and Dorian Havilliard have been hunting for the Crochan witches. They are currently in the White Fang Mountains. Manon is worried that Dorian might have to be the sacrifice to forge a new Lock.
Edda decides to let her hair return to her natural hair color, white, because it blends in with the surrounding landscape. Briar decides. to keep dying her hair black because she believes one of the Shadows has to be able to blend in at night. The Shadows continue to scout for Ironteeth patrols.
The next day the group is preparing to move on when Manon is attacked by a mighty, white bear. Dorian freezes the creature with his magic and it shape-shifts into a Stygian spider. The spider is Cyrene, the spider who Manon encountered to get spidersilk for Abraxos’ wings. She tells Manon that she tracked her scent using her belongings left at Morath. She says that there are Crochan witches nearby.
Cyrene leads the group to the Crochan witches who greet them with mistrust. Glennis Crochan introduces herself as Manon’s great-grandmother. When two Yellowlegs covens attack, Manon, the Thirteen, and Dorian, help the Crochans kill them, which gains them some trust. Dorian realizes that Manon deliberately attracted the Yellowlegs to try and gain the Crochans’ trust. Manon and Dorian explain that they are there to ask the Crochans to fight against the Ironteeth witches and Erawan’s army.
Glennis tells her that only a Crochan Queen can summon them to war, and Manon has not been accepted. She says that they are on their way to Eyllwe to answer a call for aid by the southern hearths. The group and the Crochans are delayed for a week while they heal from the Yellowlegs attack. The Shadows return from scouting ahead and inform the group that the rendezvous site with the southern hearths “reeks of death.” When the group is too late arrive in Eyllwe, Edda helps bury the dead, earring some more respect from the Crochans.
When the Thirteen and Manon go to the Ferian Gap to speak to the witches under Petrah Blueblood's command, Edda is there. Back at the Crochan camp, a Crochan scout reports that Terrasen has sent out a call for aid. Manon, as the Queen of the Crochans, spreads the Flame of War to call all Crochan witches to aid Terrasen in the fight against Morath.
Orynth readies for battle as the Ironteeth aerial force approaches, 1,000 strong. Fortunately, Manon arrives at the same time with the Thirteen and 5,000 Crochan witches. The surprise buys them a day. The next day during the battle, Abraxos is hurt and Manon is unable to stop the Thirteen as they sacrifice themselves by performing the Yielding in order to bring down the final witch tower before it can destroy the castle. Edda and Briar go still firing arrows that find their marks.
