Ciel System

The Ciel System (システマ・シエル) is a new energy source developed by Ciel in the Mega Man Zero series. The system was named by Cerveau, the Ciel in the name being an acronym that stands for "Convergent Ignition by Energen Linkage". The Ciel System has the shape of a pink lotus flower.

History
The Ciel System was developed by Ciel in order to end the energy shortage from Neo Arcadia, also ending the dispute caused by it and the persecution of innocent Reploids. By analyzing Crea and Prea, Ciel was able to create the energy system within the two months between Mega Man Zero 2 and Mega Man Zero 3.

After its development, Ciel secretly sent a sample of it to Harpuia so they could end the war between the Resistance and Neo Arcadia. However, this was not possible due to the appearance of Omega and Dr. Weil. After Dr. Weil and Copy X obtained the Dark Elf by killing several humans, they tried to convince Ciel to give them the Ciel System to combine it with the Dark Elf and generate great amounts of energy, but Ciel refused as Weil could not be trusted. After Zero defeated Weil, the Ciel System solved the energy problems from Neo Arcadia and brought peace, becoming an important discovery that changes the very foundation of the world, and brings the field of energy research into a new era.

In Mega Man ZX, the top of Slither Inc.'s head office was based on the design of the Ciel System, with the company possibly using the Ciel System to solve the energy crisis. The Ciel System flower design is also present in the rematch rooms and in the Guardian Base engine room.

Characteristics
The basic principle of the energy system consists of using a small amount of Cyber-elf energy and having an Energy Crystal as a catalyst to produce great amounts of energy. Its creation is apparently related with the improvement of Cyber-elves in Mega Man Zero 3 and 4, as Ciel spent a long time researching them.

Other appearances
Ciel System is one of Ciel's abilities in Rockman X DiVE. When used, Ciel places a lotus with an energy field around it. Enemies that enter the field will move slower.

Trivia

 * As the theme music from Ciel's Amidakuji-like minigame from Mega Man Zero 3 is called "Labo - System-a-Ciel", the minigame may be based on Ciel researching the Ciel System. In the minigame, Ciel links colored jewels to the right colored beaker to form an energy. When four jewels of the same color are combined, they form a crystal-like object, similar to a Refractor. A similar object can also be seen in the Baby Elf factory, in the room where Zero faces Cubit Foxtar, presumably being the sample Ciel gave to Neo Arcadia. However, it is also possible that those may be Energy Crystals with a different design or a completely different and unrelated energy source.
