Koh Rabntah is a researcher for the Sons of Saint Coinach in Final Fantasy XIV, tasked with researching and cataloguing the newly resurfaced Crystal Tower. Upon discovery of an orb in the unearthed tower, Koh was possessed by the spirit of the Allagan archmagus, Noah [ˈnoʊ.ə], known for her treatises on the cosmos and her oneiromancy. Noah was the court-appointed instructor for Unei and Doga, members of the royal bloodline, and transmitted her soul into an orb that survived for three astral and umbral eras until being discovered by Koh.
History[]
Final Fantasy XIV: A Realm Reborn[]
Koh's colleague, Syele, entrusted the Warrior of Light with finding Koh after she abandoned Saint Coinach's Find in Mor Dhona for Revenant's Toll. The Warrior discovered that Koh had been possessed by the soul of Noah that had transmitted her soul into the orb.[1] Noah, discovering the Warrior of Light as being part of the Nominated Observers of Artifacts Historical, offered to use their oneiromancy to ascertain the group's discoveries within the Crystal Tower, creating oneiromatic pearls that would contain the memories of the Warrior of Light's expedition through the tower. Noah promised that if she found their discoveries worthy, she would impart some manner of knowledge unto the group. Upon reviewing the Warrior of Light's memories, Noah deemed it necessary to partially inform Koh's colleagues about her presence in Koh's body.[2] Noah returned Koh control of her body, though she often took the body out for nights of debauchery.[3]
Final Fantasy XIV: Endwalker[]
Following the return of the Final Days and the Warrior of Light's victory over the Endsinger, Noah learned from Rammbroes Zasertylsyn of the Warrior's involvement with Amon and his role in the events that transpired. Speaking to the Warrior of Light, Noah requested that they summon G'raha Tia and join her in the Eight Sentinels at the base of the Crystal Tower as part of an expedition. There, Noah arrived wearing new garb obtained from Rowena's House of Splendors to make up for Koh's lack of aetherial capacity, and explained that beneath the Crystal Tower lie an ancient Allagan laboratory, known as Eureka Orthos. Here sensitive research was carried out, such as cloning, eikonic control, weapons development, and prototyping for Dalamud. Noah informed the Warrior and G'raha that she could use her control over teleportation magicks to take the Warrior to the gates of the labyrinth and G'raha's will allowed them open them thanks to his royal Allagan blood. She requested that the Warrior observe the secrets of Eureka Orthos and bring them into the modern day. Despite his desire to accompany the Warrior of Light, Noah asked G'raha not to, as he was tied too strongly to the Allagan Empire, and Eureka Orthos was not meant to inspire hope unlike the Crystal Tower. Together with him, Noah activated the teleporter and called for researchers from the Sons of Saint Coinach to organize the expedition and appraise any rarities. Before they delved in to Eureka, Noah offered the Warrior a suit of armor and aetherpool arms to counteract the labyrinth's wards, as well as a demiclone generator to assist them.[4]
Koh/Noah's new outfit.
Once the Warrior returned from the thirtieth floor after defeating a clone of the great wyrm Tiamat, Noah asked them to summon G'raha once more for both her and Raha to hear of the Warrior's expedition. After hearing of the Warrior's journey, Noah recounted Xande's conquest of Meracydia, and expounded that Tiamat's capture and cloning was meant to hasten the subjugation of dragonkind by the Allagans, while simultaneously assisting in perfecting the containment of the eikonic Bahamut. When G'raha showed compassion for both Tiamat and her clone's plight, Noah noted that times had changed, and expounded on her, and the Allagans', perspective on their works, admitting that the Warrior of Light might not view their deeds as morally right. She described their civilization as thriving on bending nature to its will and how Allagan science was one manifestation of this. G'raha asked if there was a pressing reason for sending the Warrior of Light into Orthos, but Noah just wanted to share her her pupils' work. She clarified that most of the research in Eureka Orthos was not done by her, but by the royal siblings Doga and Unei, who were wholly devoted to their research and the betterment of the people of the Allagan Empire. Noah further explained that Eureka Orthos was only one of many Allagan facilities, and she would be grateful if the Warrior of Light could find and explore more of them, and further invited the Warrior to dive deeper into Orthos.[5]
Following the Warrior of Light reaching the bottom of Eureka Orthos and vanquishing the Excalibur, Noah recounted the history behind the being: once there existed an eikon capable of creating things from nothing, which later became known as Eureka. Eureka had created trigger weapons without the need of auracite, and one such weapon, the Excalibur, was used by an Allagan assassin to slay Artorius, the resurrected king of a subjugated nation that plotted with the rebellion and Phlegethon against the Allagan Empire. This self-same weapon transformed him into the being Excalibur, which was then controlled and used to crush the rebellion and capture the rebel hero Phlegethon and transform him into a weapon himself. With all of her secrets revealed, Noah intended on leaving Koh's body but was stopped by Koh. Koh insisted that Noah stay and share more of knowledge with her, which Noah agreed to.[6]
Characteristics[]
Appearance[]
Koh Rabntah is 28 years of age and a Keeper of the Moon Miqo'te of around 62.6 ilms in height, with pale skin, dark hair and fur, and a long tail. She has pink eyes and wears inspector's eyeglasses dyed regal purple and the cotton robes common among the Sons. Noah's appearance during her time alive in her own body is unknown. Once the expedition into Eureka Orthos begins, she wears modified metallic silver moonward top of healing and Scylla's culottes and boots of casting. She wears a high Allagan earring of aiming, an empyrean necklace, lunar envoy's bracelet, and ring of fending, including an Allagan ring of aiming. Koh had some input on the garb, shooting down flashier outfits, while Noah wanted an outfit that gave her more magical aptitude.[4]
Personality[]
Described as timid and shy, Koh Rabntah was not one to stray far from the expedition camp, which led to their worries when she left for Revenant's Toll. The archmagus Noah, meanwhile, is both boisterous and curious, bragging about her many famous deeds and taking over Koh to walk in the world again. Noah, for her part, considers the members of NOAH her disciples as they bear her name and is open to imparting on them knowledge. Following her observations of the Warrior of Light's journeys, Noah remains content with observing a world not preoccupied with the mistakes of the Allag.
Noah, in Koh's body, holds a smoking pipe but it is unknown if Koh herself partakes in the vice. Indeed, Noah is known for drinking in excess, calling attention to herself and participating in debauchery all while in Koh's body, leaving the young woman flustered and preoccupied when her body is returned to her.[3] Despite these embarrassments, Koh sees playing host to Noah an opportunity to learn from the Archmagus' immense knowledge.[6]
Behind the scenes[]
Koh Rabntah served as a quest NPC for the repeatable quest 
The Gift of the Archmagus, introduced in patch 2.5, "Before the Fall". The quest, requiring players to replay the entirety of the Crystal Tower raid series to obtain materials needed to upgrade Ironworks gear, which had long become redundant, was removed with patch 6.3, "Gods Revel, Lands Tremble". Following this Koh's role was changed, now being tied to the new Deep Dungeon, 
Eureka Orthos.
Etymology[]
Noah is a Hebrew masculine name (נֹחַ Nṓaḥ), meaning "rest" or "repose". In Abrahamic religions, Noah was the tenth and last of the pre-flood Patriarchs famous for the story of Noah's Ark.
Noah is also a Hebrew feminine name (נֹעָה Nōʿā́) with a different etymology, meaning "movement". In the Book of Exodus, Noah was the name of one of the five Daughters of Zelophehad.
Noah, like much of the Crystal Tower content, is based on events and characters from Final Fantasy III. In that game Noah was a powerful Magus that had as his disciples Unei, Doga and Xande, whom he gifted control over dreams, vast knowledge of magic and mortality respectively.
