Lion El'Jonson: Lord of the First
Book 13 in The Horus Heresy Primarch Series
Each primarch is an exemplary being, derived from the Emperor’s own genetic stock to embody a facet of His personality. Their powers are unfathomable, but only one of them is the First. 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?
It's the start of a brand new series of 18 books focusing on the greatest of heroes, the primarchs themselves. This volume kicks it all off with a tale of Roboute Guilliman at the height of his powers, leading his legion into battle at the apex of the Great Crusade.
