Compromised in the Symbiot War, Daishan was scorched by the Stigmata Garrison. Symbiotes cannot grow anything on scorched worlds, but neither can humans. Daishan has sinced been recolonised by a small force of soldiers and Brother Battle monks, operating out of atmosphere facilities built on the planet. The planet seems to have been deserted by the once prevalent Symbiot forces, but the Imperial Army is not stupid - they know Symbiot seeds surely lay waiting to burst forth tendrils of new horrors. But there may also be a clue to beating back the monsters, and for such a clue the faithful will risk all.
