on Fate's Wikia page it states her
personal incantation for the set-up of Bardiche is "Arcus Cultus Aegeas" (アルカス・クルタス・エイギアス Arukasu Kurutasu Eigiasu)
Seeing as the phrase is written in Katakana, my understanding on Japanese is that Katakana is generally used for either names of non-native words
also alot of the names in Magical Girl Lyrical Nanoha are derived from cars such as the Ferrari Testarossa, Nissan Presea, Nissan Teana or the Subaru Car Manufacture, not to mention Bardiche is the name of a polearm that was used in medieval and renaissance Europe, especially in Eastern Europe and Russia.
So i am wondering if "Arcus Cultus Aegeas" has any other meaning to it, or if it's just some made up aria for Fate to use.
