The Grandmaster (
The Grandmaster has the appearance of a young woman with bright red eyes and long pale blue hair which reaches her legs. She wears an elaborate multi-layered black and lavender dress with detached sleeves and exposed shoulders. The upper portion of the dress is held by a gold choker around her neck and is ornamented with golden segments and a violet center line. Both the skirt and sleeves contain a edge with ruffles. A purple cloth hangs from the dress, bearing two entwined snakes in a Caduceus symbol with the Ouroboros insignia at the bottom. The Grandmaster also wears black leggings, high-heeled shoes and a long white cloak hanging from the choker and around her arms.
The Grandmaster commands a great deal of respect, love and admiration from her society, even to the extent that they would leave their former family and lives behind for her vision. She seems very apologetic, taking unto her self the blame for the lives lost and damage done in the name of the Society's goals. She is also humble, rejecting the grandiose labels her subordinates call her, stating that she is a merely a 'shadow that declares the appointed time.'
The Grandmaster started recruiting forces for Ouroboros from S.1185 onward. In S.1186,[Note 1] she invites Lianne Sandlot. Sandlot initially rejects her invitation to continue her search for Dreichels Reise Arnor's transmigrated soul. Once she finds him living a happy life as Giliath Osborne, she is relieved to find Ishmelga has not yet transmigrated along. Reassured, but wary the darkness cannot have disappeared entirely, she considers and eventually accepts the Grandmaster's invitation to serve her at Ouroboros.
The Grandmaster, however, immediately warns her for an impending crisis. The instant she took her eyes off Osborne, the darkness reared its head again. Lianne speeds to Osborne's house, but was unable to make it in time: In order to save his son's life, Osborne had made a pact with Ishmelga, who had been waiting for Dreichels' reincarnation for 200 years. On that moment, Lianne decides to help advance Ouroboros' Phantasmal Blaze Plan, absorb the strength of the five other Deus-Excellion in her Knight and slaughter Ishmelga for once and for all. She assumes the identity of Arianrhod and serves the Grandmaster as the seventh Anguis.
She recruits other Anguis in the following years. First, the ex-communicated bishop of the Septian Church, Georg Weissmann. Then, in S.1194, the Fourth Anguis and his partners from the Order of the Moonlight Horse, Kreuger of the Severing Chains and Golden Butterfly, join her side. In S.1197, Vita Clotilde leaves the Hexen Clan behind to join Ouroboros as the second Anguis.[Note 2]
In total, she recruited seven Anguis; apart from the three listed above, others that joined were the First and Fifth Anguis, along with F. Novartis, the Sixth Anguis.
The Grandmaster first appeared when Campanella reported the outcome of the Gospel Plan to her in the Celestial Globe. Unlike the Anguis, she lamented the passing of Anguis No. 3, Georg Weissmann, during the plan's execution. She also lamented the sacrifice of Enforcer No. II, Leonhardt, whom she had given his demon sword Kernviter, and demonstrated a profound sense of responsibility over both deaths. At the end of their meeting, she announces the start of the next phase of her Orpheus Final Plan, Phantasmal Blaze Plan.
Following the competition of the Phantasmal Blaze Plan, the Grandmaster appeared in the Celestial Globe taking to Campanella, Mariabell, and the First Anguis. She thanked Mariabell for overseeing the completion of the plan and returning safely. The Grandmaster also informed her 3rd Anguis that the Sept-Terrion of Fire and Earth have disappear from Zemuria, and it is nearly impossible for them to fall into human hand. She reassured her subordinates that, despite Vita’s questionable loyalty, Lianne Sandalot’s death, McBurn regaining half of his memories, and the departures of Joshua, Renne and Sharon, everything is still going according to planned. Finally, the Grandmaster announces that 3 years yet remains until the Primordial Nothingness arrived in Zemuria. She then announce the start of the 3rd and final phase of the Orpheus Final Plan, the Eternal Recurrence Plan.
Following the completion of the Phantasmal Blaze Plan, Campanella and Mariabell reported to her the results.
While making preparations for the Eternal Recurrence Plan, the Grandmaster's face is seen for the first time in Trails into Reverie, meeting with McBurn in the Celestial Globe. She praised McBurn for reaching this place, despite only having half of his memories and having to do so without Campanella’s guidance. Likewise, McBurn expressed suspicious of her true identity, claiming that she would be able to herself if he found she truly was. She informed McBurn that he must fulfilled his role as the Guiding Flame because he is Enforcer No. I, and confirmed to found a candidate for the Seventh Anguis, who have yet to give her a response. At the same time, the Grandmaster meet with Roy Gramheart, Calvard’s newly elected president. She congratulates him for his successful election and comment on how he different from the Blood and Iron Chancellor. Finally, the Grandmaster accepts Gramheart’s proposal that neither side would medidos in the other’s affairs for two and a half years.
- In S.1206, it was "20 years" ago. It is unknown whether Ouroboros already existed or whether Lianne Sandlot had already assumed the alias of Arianrhod. Arianrhod severed her ties with Roselia, whom she met for the first time in "approximately 20 years" in S.1206.
- From S.1204, this happened "7 years ago", and "half a year" later after Vita Clotilde left the village as a "wandering witch", putting this event in the first half of the year.
