Lion El'Jonson: Lord of the First

As the Emperor gathers his mightiest sons for the assault on Ullanor, Lion El'Jonson takes the Dark Angels the other way, to the far edge of the known galaxy, to bring one defiant world into line. His brothers see it as more of the Lion's famous pride. Out among the dead empires of the Ghoul Stars, the primarch of the First Legion may be chasing something he will not explain even to his own warriors.
