Lion El'Jonson is the paragon of what it is to be a primarch. His Legion, pre-eminent for most of their long history, typify the virtues of temperance, pride, and martial excellency that the Lion embodies. They are the Emperor's last line and final sanction. They are His Dark Angels. Now, while the Emperor gathers His mightiest sons for an assault on Ullanor Prime, the Lord of the First instead draws his Legion to the farthest reaches of the known galaxy, seeking to subdue a single rebellious world. Is this but another example of the Lion's infamous pride, or is there more afoot amidst that graveyard of empires that is the Ghoul Stars, more than the Lion will share even with his own sons?
