I'm suprised no one is talking about the progression of the ork timeline! As per the codex ghazghul after leaving Armageddon was saved by gork or possibly mork from commissar yarricks chasing fleet. Although ghazghul's weird boys died in the process ghazghul is now assembling a galaxy wide waaaagh! Sounds like he'll accomplish this before vulkan finds his long lost chia pet!

With this change in the fluff I understand ghazghul a elevated status to a lord of war! He's now on a mission to unite the galaxies orks in the past (maybe the present?). Do you think ghazghul bring him to ullanor? What are your ideas?
