Glacies Fidus

"A monarch upon the crumbling throne in the seas..."

—Somnium Fluxus

Glacies Fidus (グレィシスフィデス, Fuīdesu Gureishisu), is a seated officer within the Gotei 13; he is most notably the only Venator Scientiae affiliated with the organization. A one-of-a-kind being amongst his race, Glacies' soul was synthesized from an Anima Casus of an ancient Nefas of the same name, believed to have been one of Diluculum Sanctus' forgotten founders, and a Nefas-turned street dog named Fidus, whom Randa Primarosa adopted for a short time; hence his current name.

While Glacies has little memory of his life as a Diluculum Sanctus founder relative to that as a street dog, he is highly intelligent and fully aware of his true nature; as such, his primary ambition is to one day complete his Bibliotheca and regain his human form along with all of his memories while defying every Venator Scientiae's eventual fate of losing their supernatural abilities. Glacies joined the Gotei 13 in search of a new purpose—unlike most Venatores Scientiarum, he is not obsessed with hoarding knowledge.

Life as a Human
According to what little has been discovered of his life as a Nefas, Glacies was a confidante of Axenus Gate and one of his most trusted companions. It is said that Glacies originally opposed the idea of awakening an abstract deity and thwarted Axenus' earlier attempts to contact Agostinha, but later relented to a degree and chose to watch over Axenus during the process. Upon inheriting a superior fragment of Agostinha's power himself, Glacies became the youngest and most respected founder of Diluculum Sanctus; with a sagely wisdom unfit for his age, Glacies often served as an adviser for Axenus and the unknown third founder. The circumstances behind his death and transformation into an Anima Casus are unknown, although he is rumored to have been betrayed by an underground faction within the collective and killed long before the disappearance of the other two founders.

Trivia

 * Images drawn by the author.
 * Glacies' dog background was partially inspired by the life of the Italian street dog Fido. The name Fido is a derivative of Fidus.
 * Glacies was born on exactly the same date of Fido's death.
 * Glacies' full name means "Faithful Ice."
 * Glacies was the character originally planned for the RPCQE Exam in place of Silvio da Parma; he was delayed due the author's lack of ideas for the character at the time.
 * Glacies' Zanpakutō was originally intended to be a Water-Type, but this would have been redundant given his identical soul element.
