Sacris

Sacris is a feudal swamp-and-moor world in the Calixis Sector and the Storm Wardens' recruiting ground. Clans duel with heirloom claymores while the Chapter watches from the moon Highcastle. After the Nemesis Incident the Wardens quarantined the planet behind plague-beacons, and even they no longer know why Owin Glendwyr ordered it.
