(A part of the Story Beyond Worlds series) A collection of the many records, stories, legends, and researches, gathered by the researchers of Celestia, also known as the Flying Kingdom and Connector of Worlds. The collection displays the beginning of the journey of the most prominent factions who fought in 'War for Ultimate Authority' and 'Trials of the Goddess'. The higher authorities of Celestia, after much consideration and interviewing of the few surviving beings, declared the collection as the most accurate record of the past, going into detail of the starting points in the many journeys, all leading these many individuals to the top to fight it out for the crown. The collection also contains detailed theoreys of the 'Concept of Souls', 'Mana Compression and Ascension', 'World Systems', along with the many abilities possessed by the individuals. The collection, named 'Origin of Memories', served to deepen the understanding of all regarding the 'Functioning of Worlds and Souls', along with granting a more detailed explanation of the 'Soul Seer's eyes' after extensively interviewing 'The Empress'. It also serves to deepen the understanding of the background of 'The Empress' along with the goals of 'The Creator'.  The organisation issued two versions, a plain research document for all staff of the organisation, and the other disguised as a novel series. The only one accessible by non-authorised personnel turned out be the novel series, the one you might just be about to read.  If you happened to read the organisation's collection on the main events, published before this, then you need not worry, this only serves to deepen the understanding about the past, one should not be concerned for reading the other collection first, the organisation makes sure to explain important topics when they are first mentioned in both collections.
