Louisoix Leveilleur is a prominent non-playable character in Final Fantasy XIV. He is the leader of the Circle of Knowing, a group involved in the Seventh Umbral Era storyline. He is most notable as the NPC involved in all quests related to Primals in version 1.xx. He is voiced by David Lodge.
Louisoix is an elderly Elezen wearing an acton, armored leggings, and a horned staff—the Tupsimati—bearing the mark of Thaliak. He bears the Circle of Knowing tattoo on his forehead as well as his neck. He has white hair with a beard and a receding hairline, and closely resembles the Revs of Final Fantasy Tactics A2: Grimoire of the Rift in skin tone.
Louisoix, like the rest of the Circle, is well-spoken and informed. He is the typical wise old wizard, offering guidance and encouraging the Adventurer to overcome the daunting threat of the Primals.
Louisoix traveled from the Circle's homeland of Sharlayan to Gridania in response to the first appearance of a Primal, Ifrit. Since then he has used his skills and connections to help the Adventurer gather the items needed to enter the lairs of the Primals. He has also joined the Eorzean Alliance under Gridania's banner as their chief tactician. Gridania's newspaper, The Raven, has also credited him with initiating the Alliance's shift to the offensive, as well as ushering the Adventurer to join the battle.
During the quest Living on a Prayer, Louisoix and the Circle of Knowing marked stones throughout Eorzea with the symbols of The Twelve, and urged the Adventurer to offer prayers to each of them with the hopes of summoning the yet unseen gods.
Once the final battle before Dalamud's fall began, Louisoix supported the Eorzean Alliance. When Dalamud shattered and Bahamut escaped its imprisonment, he attempted a ritual, calling upon the powers of the Twelve to re-imprison the Elder Primal. The spell ultimately failed, however, and all he could do was teleport the Adventurer with an unknown spell, before the dragon's Megaflare ravaged the entire battlefield with Louisoix consumed in the explosion that presumably killed the majority of the people present in the area.
During the aftermath, Louisoix's shattered staff was recovered by Kan-E-Senna and returned to the Scions of the Seventh Dawn (the successors to the Circle of Knowing), where Minfilia kept it in her office.
But what many did not realize was that Louisoix resurrected after his death, having his prayer for a means for Eorzea's rebirth during the Seventh Umbral Era answered by becoming the Primal Phoenix after being infused with some of aether left behind by his earlier attempt to seal Bahamut. Louisoix used his newfound power to defeat Bahamut while returning life to Eorzea. However, before he can return the aether he absorbed to the land, Louisoix is grabbed by what remained by Bahamut and ended up in the Binding Coil of Bahamut as a thral to the Elder Primal to oversee his. When the During the Adventurer and Alisaie's journey into the Binding Coil of Bahamut, Louisoix has been watching the party since they destroyed the ADS in Turn 1 and disappeared before being noticed. Following the defeat of Twintania, Alisaie sees her grandfather with an imitation of Nael Deus Darnus as they depart further into the Binding Coil.
In the Second Coil of Bahamut, Loiusoix makes his presence known by silencing Deus Darnus before he could speak to Alisaie after she and the Adventurer reached the 4th turn. Louisoix presents himself as another thrall of Bahamut while warning Alisaie not meddle in the Primal's resurrection with the threat any further and should they refused to do so he will not hold back against her and the Adventurer.
Within the Main Bridge of the Final Coil of Bahamut, Louisoix appears before Alphinaud, Alisaie, and Adventurer. He reveals the origin of Bahamut and how the dragons of Meracydia and the Elder Primal were imprisoned within Dalamud by the Allagan Empire in an attempt to further enhance their power. Louisoix then berates humanity and tells them that there can never be peace as long as humanity exists. By then, Alphinaud exposes Louisoix's new nature as Phoenix before the Primal is defeated. After the battle, Louisoix reveals the events that transpired during his confrontation with Bahamut. Freed from Bahamut's control upon his defeat, Louisoix tells his twin grandchildren to find their own paths while giving them the means to summon his Phoenix incarnation, and gives Alisaie peace of mind before opening a portal for his grandchildren and the Adventurer to end Bahamut's resurrection once and for all.
After Bahamut's final defeat, Alphinaud and Alisaie decide to keep Louisox's transformation into Phoenix a secret, fearing that if it became known, people seeking salvation might attempt to summon him, which they knew would be against his wishes.

- It is implied that the horn on the Tupsimati is similar to the horns featured in 1.0 main storyline quests.
- As part of a New Years greeting from the development team of A Realm Reborn, Yoshida included a prophetic verse from Louisoix. Upon careful comparison between language versions, the consistent message implies one of two entities will decide the fate of the world through actions taken on the Primals: one entity of light and one of darkness/might.
