As I was admiring the new Legion of the Damned models from Gamesday Italy I was struck by the thought------- Could this be one of the "Lost" Legions?
After all they mysteriously appear when most needed & disappear again after victory (or defeat).
So maybe they lurk in the Warp waiting to fulfil the Emperors will but whatever happened to them back in the far past does not allow then to have a continuing presence in real Time/Space.
Could the Emperor have planned for this to be their Fate?
What are your thought folks?
