Operation Orb

An Operation Orb (演算宝珠) is a tool mages use to interfere with reality through magic according to their will. A breakthrough to recreate miraculous phenomena through combination of both mana and analog calculation.

Not much has been revealed about the inner working of Operation orb, but the orb's main function is to process the world data and convert mana of user mages. The Great Powers had developed a cutthroat competition in researching this technology. In second chapter of Deus lo Vult it's revealed that Empire is the pioneer of this aspect of magical technology with their Chief Engineer  Adelheid von Schugel.

The man also responsible for keeping Empire's superior standing in magical technology, which is achieved through practical implementation of dual-core operation orb, which is called Elinium Type 97 ‘Mobile Assault’ Operation Orb.

History
During industrial revolution, magic went through revolution following other field of study that influenced by war. In their search to optimize spell composition, the analogue computer Differential Analyzer caught their attention. Inspiring engineer to duplicate computerization by magic and invent the modern magical device, Operational Orb.

The design of magical computer that facilitate mages to compose spell is based on pocket watch. Making Operational Orb a device that compact, sturdy and precise.

Mk. 13 Operation Orb
The Operation Orb Tanya used in beginning of the series made by Folkerr Factory.

Elenium Type 95 Operation Orb
Developed by Adelheid von Schugel and his team as the first multi-core operational orb. It uses 4 cores as opposed to using only 1 like normal models do, quadrupling the output of an Operation Orb that uses mana in place of fuel, but at the cost of mana consumption rate increase by four-fold. The Type 95 is an experimental revolutionary Orb which theoretically allows the user to reach an altitude of 18,000 feet and cast multiple spells; however it is very unstable and fragile, with a very high chance of exploding.

Thanks to Existence X Tanya is the only person in the world who can safely use the Type 95 by praying to "God" or "Being X". Achieving even miraculous deed of materializing mana to the world, a technology that 1000 years ahead of the present. Existence X has also modified the orb to cause Tanya to gradually become more faithful to him whenever she utilizes it, much to her ire.

Elinium Type 97 ‘Mobile Assault’ Operation Orb
An Operation Orb with 2 cores developed by Professor Schugel, a product version of Tanya's Elenium Type 95 that couldn't be mass produced. The principle of this orb is the same as Elenium Type 95, but more stable and far inferior output.

However this Orb is still a generation ahead of existing Orbs used by other country.
