Veridical Codex Lux
Episode Two

Warning This Section Does Contain Spoilers

The Codex has a book cypher within its pages. On pages 18-19 is the "Birth of the Glorious Paragons", the history of the Family. We notice that some of the dates are actually dates, can't be dates, but are locations within the book itself. Such as: 11/144/1809 (page 11, word 144). Using all of the dates that have this format we come to a solved sentence of:

3/2/1706 = The

11/4/1734 = Raven

9/30/1737 = is

9/31/1847 = not

3/22/1856 = eternal

7/13/1974 = and 

11/105/1762 = will

11/144/1809 = be

11/145/1832 = unmade

9/48/1745 = without

3/36/1934 = face

The Raven is not eternal and will be unmade without face.
