You can consider this the inauguration of a series - to insofar as possible, commemorate the events behind Sabatp's song on the anniversary of said events. I haven't mapped all of them to a calendar yet, so things may be incomplete for a while, but I've already seelcted dates for each song in The Great War.
Today marks the anniversary of one of the first raids conducted by the Arabs in conjunction with T.E. Lawrence "of Arabia" against the Ottoman Empire. Incidentally, the story of Lawrence is arguably a major influence on the story of Dune.
