Many billions of years ago in space, a powerful, spiritual entity divided itself into two lesser beings that began to fight one another. After a long and arduous battle, there was a victor. The winner banished the enemy spiritual life form into another dimension. The victor was called "The Great Light" and the defeated one became "The Profound Darkness". The Great Light feared the possibility of the Profound Darkness resurrecting itself, so it placed a seal over the dimensional portal. The seal was three planets revolving around one fixed star: the Algo Solar System. The Great Light then divided the responsibility of the seal between three races of "Protectors": the Parmians of Parma, the Dezolians of Dezolis, and the Motavians of Motavia. However there were fluctuations in the strength of the seal; once every 1000 years, the seal would weaken drastically. Future generations of "Protectors" would also forget their mission. As a contingency plan, The Great Light created the fourth planet Rykros, which returns to Algo once every 1000 years, as well as its inhabitants such as Le Roof, to remind the protectors of their mission when the seal's final moment came.
During its time of imprisonment, the Profound Darkness was seething with animosity and the desire for vengeance. Once every one thousand years, when the strength of the seal is abated, the most intense part of the Profound Darkness' spirit of hate leaves its dimensional prison and arrives in Algo in physical form. This extension of the Profound Darkness is known as Dark Falz. Through Dark Falz, the Profound Darkness would devise various machinations in Algo to bring about the destruction of the seal.

In Phantasy Star Online 2, the Profound Darkness was created by Photoners through their experimentation to create a copy of Xion. During its creation process, the negative emotions within the Photoners caused its photons to become corrupted which resulted in the creation of the Profound Darkness. Immediately after its creation, the Photoners sealed the entity away due to fear of the monstrosity they created. However, despite being sealed away the Profound Darkness continued to influence the universe through its seal, even creating numerous Dark Falz to gather enough corrupted photons needed to break its seal.
