 With the number of Daeva growing, the Lords decided to form an army, with ten of the Empyrean Lords leading the Daeva into battle; while the remaining two, Siel and Israphel, protected the Tower of Eternity (thus earning the title "Tower Lords").This conflict between the Balaur and the Empyrean Lords would come to be known as the Millennium War, which led to no real progress by any side.As the war progressed, a faction of Lords began to view the war as unwinnable, and Lord Israphel proposed a discussion of peace with the Balaur.
