Investigation of Helvetis's Death
Jenna has resigned from the Temple Knights to pursue a a career as a Blacksmith. Sinead has requested the Milletian to investigate Helvetius's death by finding Jenna. The Milletian is asked to interrogate her in order to obtain any information regarding Helvetius. The Milletian visits Priest Collen, who is surprised to get a letter from the Royal Regime. As Jenna's guardian, he feels uneasy about anything regarding Jenna. Collen, trusting the Milletian, tells them where Jenna can be found. The Milletian then rushes to Taillteann's Stonehenge and searches for Jenna.
After searching Shadow Taillteann, the Milletian finds Jenna near the Alchemist's House. Jenna says that she has been expecting them, as Collen told her ahead of time. Jenna explains that she has been hunting the Corrupted Alchemists for a long, swearing to avenge her father and her childhood. She confirms that Helvetius was killed before her very eyes, at the hand of his own Flame Burst. Jenna then mentions that Collen still has contacts in the Temple Knights organization. According the the Temple Knights, Helvetius has been sighted alive. Jenna then disregards anything concerning Helvetius. She then refers the Milletian to James, who is an investigator sent by the Pontiff's Court.
Forging the Temple Knight Coat of Arms
After hearing the whereabouts of Jenna from Collen and receiving the blueprint for the Temple Knight Coat of Arms, the Milletian rushes over to Shadow Taillteann. Meeting Jenna in front of the Alchemist's House, she explains that in order to enter the Lair of the Temple Knights in Rundal Dungeon, a special pass must be forged in order to enter. Since Jenna is no longer a Temple Knight, she does not have the materials necessary to forge one. Jenna requires the blueprints and six items needed to forge a replica. The Milletian assists Jenna in obtaining the materials.
After obtaining the necessary materials, Jenna begins to forge the Temple Knight Coat of Arms. The Milletian takes the newly forged coat of arms and head to Rundal Dungeon.
Obtaining the Forbidden Book "The Battle of Mag Tuireadh"
As the Milletian enters the Temple Knights Lair, they are greeted by Jenna. Jenna swore to never set foot inside the Temple Knights Lair. Jenna feels strange setting foot back inside the lair, but she is willing to do so in order to help the Milletian obtain the forbidden book regarding Nuadha's past. The Milletian and Jenna finds the book at the end of the Lair, but it requires deciphering, as it is written in Druidic dialect.
The Alchemist War
Jenna and Leymore has gotten word that the Royal Alchemists are about to confront the Corrupted Alchemist, beginning to start a war between the Factions. Jenna says that she is not at Shadow Taillteann out of hatred or vengeance, but to confront her past. The Milletian agrees to help them both and head towards the square, where the war begins to escalate. Although she is prepared to attack the Corrupted Alchemist, Jenna is struggling to hold her weapons and is feeling uneasy about the whole situation. Upon arrival, they are greeted by Lennox. Jenna stands idly by as Leymore and his father talk to each other. Cai then butts in, telling the two family members to stop fighting and worry about more important matters, such as taking care of the Corrupted Alchemists.
As the battle draws to a close, the Milletian, Jenna, Leymore, Cai, Lennox, and the Royal Alchemists corner Helvetius. As a finality act, Helvetius overloads all the nearby Alchemy Ovens and causes them to self-destruct. The group begins to escape, running away from the fierce flames produced by the self-destructing ovens. Jenna trips near an oven that has yet to explode. Lennox, realizing that it will soon self-destruct, runs to Jenna's aid and places a Barrier Spike close to Jenna, shielding her from the explosion. Lennox was caught in the blast, as he was too close to the explosion, and is fatally injured. Leymore then calls out to him and rushes to his aid. Lennox hoped that Leymore would someday understand why he uses alchemy the way he does. He regrets that he should told his son sooner, then asks for his son's forgiveness with his dying breath.
The Fragments of Falias
At some point Jenna told Karpfen about the location of the last treasure of Falias, Golden Apple. Jenna sends word to the Milletian to visit Karpfen about the details. According to Karpfen, the location of the last treasure is heavily guarded by Shadow Monsters and the Golden Apple aborsbs the monster's Erg. The Fomors have been causing a ruckus due to an unknown reason, but the likely cause is their reaction to the Golden Apple.
Morrighan had summoned the Milletian, Leymore, Cai, and Jenna to the Underground Spring in Ceo to meet with her. She explains by finding all of the lost treasures left by the God when they descended into Erinn, the Brionac was completely restored. She tells the Milletian to use the light of the Goddess to shine the path to Holy Throne of Falias. Morrighan then gives her blessing and enchants the Brionac, but falls due to her wounds against her battle with Nuadha. Leymore and Cai rushes to Morrighan to assist her. The Milletian does the same, but is stopped by Jenna, who tells the Milletian that as the Master of the Brionac, only they can stop Nuadha and thwart his plans on becoming an all powerful god. The Milletian heeds Jenna's words and leaves to stop Nuadha once and for all.
