Story
Keyron lived with her brother Seyren, mother, and father within Rune-Midgarts. While playing hide-and-seek one day, Keyron found herself inside an Orc base where she was rescued by Seyren and their mother. As they fled, Keyron tripped and fell, causing their mother to die in order to protect her from the pursuing orcs. Seyren and Keyron were eventually rescued by Pronteran knights and were reunited with their father. Keyron cried into their father's arm as she blamed herself for the death of their mother. Since then, Keyron sought to never allow herself to be weak enough to need protection from anyone.

Her relationship to Seyren became strained when she discovers that he had chosen to hire another wizard from the guild for a mission instead of her, causing him to become greatly injured during the mission. As he was being healed by Margaretha, Keyron angrily berates him for not believing in her and vows to make him see her as someone capable.

Keyron was eager to join the clandestine operation to find the missing king of Rune-Midgarts in order to prove to her brother that she has what it takes to be a powerful asset. Their investigations led them to the city of Lighthalzen, where they split up in order to cover more area. Keyron, Seyren, and Eremes later meet up in the Lighthalzen hotel's tavern where they await the rest of their search party. Eremes is suspicious of the whole situation as they were supposed to all meet the president of Schwarzwald in the country's capital of Juno, but were notified to meet in Lighthalzen instead. They are eventually approached by a Schwarzwald guard seeking to take them to the country's president. After verifying the guard's identity, the three of them follow the guard to an underground location.

While waiting for the rest of their comrades, Keyron and the others are drugged with sleeping gas and taken by Schwarzwald guards. Eremes rescues her from the guards and the two of them hold themselves up in a room to recover. Eremes tells Keyron to rest up as she was still reeling from the effects of the sleeping gas. In the meantime, the assassin cross interrogates a scientist they came across in the room and poisoned. The scientist tries to call for help, but Eremes kills him before he could do anything. Keyron is annoyed as they weren't able to get much information from the scientist. Eremes tells her once again to rest and Keyron protests that she needed to save her brother and their comrades. Eremes points out that she's of no use in her current state and Keyron relents and allows herself to rest up.

After some time, Keyron asks Eremes about his hand, which he had cut up with a hidden dagger in order to resist the sleeping gas. He assures her that it's fine. She inquires about the dagger and Eremes simply notes that it is a simple trinket from a tiresome old man. Now that she was well-rested, Keyron wonders what their next move is and Eremes refutes her demand to rescue their comrades as his goal was to get Keyron to safety to find help while he did the rescuing. Keyron becomes infuriated that Eremes is also treating her like a child like her brother has been doing. They soon realize that they would have to fight their way out and Eremes relents in allowing Keyron to fight alongside with him. Unfortunately, Keyron becomes separated from Eremes and is soon captured by the Schwarzwald guards yet again.

Keyron becomes implanted with a Rune Stone (imitation of Ymir's Heart Piece) and placed under observation in a holding tank. Unconscious, Keyron would unleash bouts of magical energy as she is internally angered by her inability to keep herself from becoming a burden on her brother. The scientists observing her end up overdosing her on anesthesia and Keyron dies in Seyren's arms, never having proved her worth to her brother.
