After their actions on the maiden world of Agarimethea awakened slumbering necrons, the Ynnari and the Wild Riders of Saim-Hann ally once more to try and defeat the threat - but what are Yvraine's real motives for assisting? The Wild Riders of Saim Hann craftworld are renowned for their skill and daring, none more so than their headstrong Wild Lord, Nuadhu Fireheart. Having been approached by a representative of Yvraine, emissary of the Whispering God, Ynnead, Nuadhu has unwittingly awoken a slumbering threat - a tomb world of the aeons-old necrontyr.

The two forces return to Agarimethea to destroy the necrontyr before their strength becomes unassailable. But for what other purpose does Yvraine accompany Nuadhu and his kin, and what exactly is her interest in Naiall Fireheart, the ailing chieftain of the clan?
