The PCs crash land on a mining world called Hervara (after being shot down by what looks suspiciously like an Ork Fighta-Bommer), a world in open secession from the Imperium of Man. Separated from their regiment, they must survive with little more than their wits and their faith. A dark secret lurks beneath Hervara's crust; an ancient Ordinatus. The PCs must secure this asset at all costs!
It's neat to see our first glimpse of OW supplements. FFG has been somewhat all over the board with their adventure quality, but I trust them to do this well. Ordinatus devices are a cool shout-out to a rarely-plumbed section of canon. Secessionists are some of my favorite enemies in 40k; while we know little about the Severan Dominate, I hope they exist as something other than a mob of mindless cultists and deformed mutants. The art quality looks nice, and I'm curious to see what else is hiding inside this treat.
(Side note: they promised us OW corebook previews in the coming weeks!)
