Book three in the Black Library Novella Series 1, Nick Kyme’s Auric Gods is a sort of 40k-noir story crossed with an exploration of the role of the Adeptus Custodes in the Dark Imperium era. On a world at the fringe of the Sol system, peacekeeper Ursula Gedd and the shadowy Meroved – once a Shield Captain of the Adeptus Custodes, now an Eye of the Emperor – investigate worrying patterns within their city, Vorganthian. Meanwhile on Terra, three Custodians are gathered by Trajann Valoris and sent out from the Throneworld to recover a dangerous artifact, stolen from deep beneath the Imperial Palace.
