EXA PICO

Exa Pico エクサピーコ (ekusapiiko), misromanized as Exa pieco in the localization of Ar tonelico II: Melody of Metafalica, is the point of origin for the universe of the Ar tonelico series.

From the current knowledge we have on Wave Science, Exa Pico is an atomic nucleus with an incredible density, which many millions of years ago, contained all of the wave forms that comprise the universe. Then, at a certain point in time, all of the waves it contained broke off from it in a massive explosion, which is the Big Bang that created the universe. This formed all of the Dynamic Waves, which are the undulating waves that comprise energy, and when all of these waves clashed with each other in the complete emptiness of the space of that time (the Sea of Num), they gave birth to the Static Waves, which went on to group themselves and form the first atomic nucleuses, molecules, and thus, gradually giving birth to all kinds of matter.

Even today, Exa Pico and its waves (its Will) have influence over the entire universe, dictating the rhythm and beat under which the galaxies, planets and even the life forms of Ar Ciel; dance. Said Song played by Exa Pico is what the Teru of Ar Ciel call the Grand Wheel of Fate. However, not all the Wills that rule the galaxies and subordinate structures to them agree to everything that the Will of Exa Pico says, which also changes their destinies.
