The Thramas Crusade draws to its inevitable conclusion, with the forces of the Dark Angels and the Night Lords locked in a struggle which neither side can abandon.
The Night Haunter lies comatose after being mauled by his primarch brother Lion El'Jonson, and in his absence it falls to Sevatar and the remaining members of the Kyroptera to command the Legion. But the self-styled 'Prince of Crows' has his own plans to save the Night Lords from annihilation - plans he intends to follow, with or without his comrades in tow.
As a Night Lords player, this book really gets me fired up and provides a lot of potential for back stories for my army. It also gives great insight into the phyche of the Night Haunter and the legion as a whole.
