Very interesting short story collection centered on the infamous Blackstone Fortress, space station built at the very beginning of the age of Eldari, forged by the Eldar's deity Vaul. This is mysterious structure, not inert but constantly shifting, transforming from within, and capturing and integrating whatever is left or lost within at the moment of change - whole armies and fleets from various species, long forgotten mysteries and weapons, treasure beyond imagination. For all means and purposes this space station is very much like vast and ever-changing city-structure from Blame! comics.
What majority finds here though, is death and horrors. Because in depths of Fortress, itself full of weird robotic systems and unstoppable organic life-forms, Chaos worshipers are building the bridge-head, and they are getting ready to capture and control the fortress to deal the deadly blow to Imperium.
Just outside the Fortress we have Precipice, Babylon-7 type of space station where humans and alien mingle (including mutants and unsavory Drukhari) all aiming to discover that specific treasure or secret that will help them climb the power ladder.
Stories vary, from Drukhari working with Eldari to find objects from Eldari past, Drukhari hunting their kin, mercenaries working with Rogue Traders investigating the depths of the Fortress, zealot Ecclesiarchy agents seeking the Chaos corruption in the depths of Fortress so it can be purged by fire, ancient Iron Men (UR-205 is magnificent) trying to stay hidden from ever curious Mechanicum forces, and war veterans trying to escape the hell of war that is Warhammer 40k, the last Longhorns, and definitely my favorite characters in this collection - ratlings and brothers Raus and Rein, veteran snipers and for all means and purposes W40K version of Lucky Logan's.
Very interesting story collection, I thoroughly enjoyed it. Weren't it not for high temperature and inability to do anything but sleep on and off during the hot summer :) I would finish the book much earlier. As it was it took me almost 2 weeks, but not because of the stories themselves.
Highly recommended to all fans of W40K.
