Arius Sabaramond

Arius Sabaramond (アリウス・サバラモンド Ariusu Sabaramondo) the "Shiranui Sky Tower" (不知火天楼 Shiranui Tenrō) is the former first-ranked Imperial Court Sorcerer of the Byandy Empire.

Appearance
Judging from Sabaramond's silhouetted appearance, he appears to match Easlies Swordfrail in height (disregarding her hat) but in contrast has short hair and extremely large loop earrings. While serving the Byandy Empire, he wore a light-hued robe with a large hood.

Personality
Sabaramond's confrere Corpse God remembers him as a kind man renowned throughout the empire, always drawing crowds whenever appearing at public events; his popularity would be directly comparable to that of a celebrity or idol.

Easlies Swordfrail in her cynicism suggests that whomever serves as head of Byandy's court sorcerers is inherently half politician, insinuating to some extent that Sabaramond's amicable socializing has a political bent.

Chronology
On the first day of Corpse God's journey as Easlies' necromancy student, Sabaramond overhears Easlies' declaration that ability alone is not enough to make one the first-ranked Imperial Court Sorcerer, let alone the second- or third-ranked sorcerers, and approaches to disagree: in his opinion, Easlies would qualify for first-rank solely based on her ability.

Rather than acknowledge such praise, Easlies cynically quips to Corpse God that Sabaramond is already appraising him as a potential instrument of future court politics. Sabaramond refutes this perspective, arguing that all people have equal value and cannot be evaluated in terms of price. His outlook seems to leave an impression on Corpse God, who will remember him as a kind person a century after the fact.

Many years after this interaction, the Byandy Empire abruptly collapses. What becomes of Sabaramond after this event is unknown, and his survival has yet to be confirmed. It is entirely possible that he still lives, as a sorcerer of his caliber would be more than capable of slowing down his aging process and extending his life by a century or two.

The Bastard Children of Sabaramond
A mysterious group known as the "Bastard Children of Sabaramond" exists on Earth in modern times. Fire-breathing Bug is openly hostile toward them and appears to be actively pursuing their destruction for the sake of vengeance. Moreover, "Sabaramond" as a name and "Sabaramond's protection" have been invoked more than once by others; specifically, by Hideaki Habaki and Kuon Higuro.

Habaki has asserted that 'Sabaramond' is the name of an information channel he has hired; if true, it appears that Higuro is a member of this alleged channel. Higuro has previously invoked Sabaramond's protection when referencing the five-year-old incident with Miyabi Hosorogi during an Agakura business call. Additionally, "Sabaramond's protection" appears to be associated with phenomena that bend the laws of nature; Higuro reports Misaki Sakimiya's inexplicable return to life as something potentially related to "the protection of Sabaramond" when calling Habaki.

When Fire-breathing Bug accuses Corpse God of being a bastard child of Sabaramond, Corpse God immediately associates the name with his former colleague and asks if Sabaramond is on "this side." He also demands to know whether Fire-breathing Bug is from the Empire or the Nyanild Kingdom, though, curiously, Fire-breathing Bug does not seem to recognize Nyanild as a word. Whether Arius Sabaramond is directly involved or otherwise connected to this group is unclear, but the link to and pertinence of his name are impossible to miss.

Trivia

 * In Japan, 'shiranui' (lit. 'unknown fire') refers to an atmospheric optical phenomenon described as 'ghost lights' from Kyushu: a phenomenon in which 'flames' can be spotted in open water several kilometres from shore; these flames then multiply into hundreds or even thousands of flames in a row which may span four to eight kilometres in length. This phenomenon, which continues to occur in the present day, has been reported on for centuries; in olden times, the flames were believed to be lamps of the Dragon God.
 * The series has yet to mention this phenomenon in any capacity. It is therefore unknown whether the phenomenon exists in-universe and, if so, whether it is in any way related or relevant to Sabaramond's title.
