The Imperial shrine world of Karat-Ist is at the epicenter of a massive conflict between Imperial Forces and a huge Chaos invasion force, led by a warband of traitorous Death Guard. The planet has been largely overrun and the enemy forces are already entrenched. The entire planet is wracked by war.

Under the cover of this huge conflict a Thunderhawk carrying only a small force of five Minotaurs arrives at a vast temple complex on the blighted planet. Their mission, led by Captain Daed, is to retrieve a relic held sacred by their chapter – a precious artifact that holds the secrets to the origins of their chapter. They fear this relic falling into enemy hands and believe that – at present – the Chaos forces do not realize that the artifact is in their possession. -- From Amazon.com Product Description
