The Grandmaster (
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 in-game in Trails in the Sky the 3rd, Star Door 14: "Phantasmal Blaze". 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 completion of the Phantasmal Blaze Plan, Campanella and Mariabell reported to her the results. Once again, she lamented the many members who left Ouroboros during the completion of this plan, but reassures that it was all within her projections. She states that the lifespan of Zemuria has been extended a little due to averting the Great Twilight, and that three years remain until the "Primordial Nothingness". She then announces the start of the third and final phase of the Orpheus Final Plan, the Eternal Recurrence Plan.
While making preparations for the Eternal Recurrence Plan, the Grandmaster's face is seen for the first time in Hajimari no Kiseki, meeting with McBurn in the Celestial Globe. McBurn was suspicious of her true identity, claiming that she would not be able to hide herself if he found out who she truly was, which she agreed with. At the same time, she also entered a truce with Roy Gramheart, Calvard's newly elected president, in which neither side would meddle in the others' 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.
