Final Fantasy XIV (version 1.0)
Along with Greinfarr and F'lhaminn, Niellefresne aided in running a parade in Ul'dah. As the parade was underway, a goobbue suddenly broke free from its fetters, knocking over its carriage and injuring F'lhaminn. Thancred jumped in to distract the rampaging beast as the civilians evacuated, with Niellefresne escorting F'lhaminn to safety. After being subdued, the goobbue stormed in another direction and crashed into a wall, knocking Warburton into a coma. These events were later witnessed by the adventurer in an echo flashback.
The adventurer went to the Goldsmiths' Guild to sell one of F'lhaminn's flowers from the parade. They were taken back in time and met Niellefresne who noticed that the flower did not wilt and offered to pay them for compensation. In another Echo flashback, Niellefresne appeared at the Gladiators' Guild speaking with Greinfarr about how Ul'dah was in need of a reformation.
In what appears to be the Platinum Mirage, Thancred played a betting game for Niellefresne to admit the truth to everyone present. Thancred explained there were merchants in Ul'dah looking to profit off the war with the Garlean Empire, and there were people looking for fame and glory in the people's time of need. Niellefresne did not admit to any of his claims and left.
Outside Ul'dah, Corguevais planned on taking Ascilla back to Ala Mhigo, but Niellefresne and the others disagreed. He revealed Ul'dah was in danger from a threat worse than the Empire. Uninterested in the girl, Niellefresne worried about the safety of Ul'dah. Corguevais blew the horn that caused the gobbue to go rampant in the parade, summoning a horde of coblyns. As he escaped, Ascilla was left behind and attacked by the creatures. F'lhaminn defended her, but was knocked unconscious. Niellefresne asked the adventurer to help them fight, and after the battle, they took F'lhaminn back to Ul'dah. The group discussed what Corguevais meant by the threat and assumed him to be a Garlean spy. F'lhaminn awoke and told the group to seek out Thancred who was investigating the Garleans and exiled for unknown reasons. Niellefresne promised to look into the matter himself.
Niellefresne planned on resurrecting Warburton to retrieve the information he had, as well as to atone for causing his death. As he was about to prepare the corpse, he was startled by what he found in the coffin before a robed man appeared from behind and stabbed him in the back. Thancred and the adventurer found Nielle, who pointed to Ascilla shortly before passing away.
Ten years later, Colbernoux stated that Niellefresne had fled with the Heartstrike, a blade capable of restoring life to the dead. When Niellefresne was murdered, the Heartstrike's powers awoke, preventing Niellefresne's body from deteriorating. Colbernoux claimed that his only wish was to send a soul from his brother to the kingdom of Thal, where he could find peace. However, he did not know how.
The Warrior of Light investigated Niellefresne's murder along with F'lhaminn and several of their old companions, and discovered that the weapon used to kill him was the necromantic blade Heartstrike. Although it was designed to raise anyone struck by it as an undead, its enchantment had weakened, and instead merely preserved Niellefresne's body, preventing his soul from moving on. With the help of Severian Lyctor, the Warrior of Light destroyed the remaining enchantments on Heartstrike, allowing Niellefresne's soul to depart, and giving F'lhaminn and her friends the chance to say their farewells.
Niellefresne is a tall Elezen with gray hair and blue eyes who wears round glasses. His clothing marks him as a well-to-do person in Ul'dah. He wears a bright red vest, likely velveteen, with dark brown leather lining over a black shirt, likely velveteen as well. His pants are silvery-white and his shoes black with pointy tops.
Niellefresne cares deeply for F'lhaminn, as the two were lovers. He worries about the well-being of Ul'dah and believes it needs to be reformed. Though he appears callous when showing no remorse for the death of Warburton, deep down he cares and feels he must atone for what he's done.
Niellefresne appeared as a guest NPC during Ul'dah's Main Scenario Quests Flowers for All and Calamity Cometh in version 1.0. He did not attack enemies, but instead healed the player with Potions if their HP got low.
