The Iron Warriors’ campaign of destruction on Tallarn turned a once-verdant agri-world into an inhospitable desert, and you can read all about it in The Devastation of Tallarn. This hardback book introduces several varieties of Legions Imperialis campaigns, such as the advanced Breakthrough Campaign in which you aim to defeat enemy strongholds, or the Northern Desolation campaign which includes Fog of War and Spearhead Assault battles. There are also Battle Honours, Veteran Detachments, Formations of Legends, and new Formations and Detachments for the Legiones Astartes and the Solar Auxilia.
