In summary:
* The engineer corps Adeptus Vaubianis discovered the planet Xuanji Tu.
* Being imperial nutjobs, they turn the planet into a fortress, following Rogal Dorn's designs.
* Because they are so obsessed with Rogal Dorn's designs, they do not respect the planet, treating it as purely raw materials.
* There is a spiritual locus in the design that the engineers didn't understand the significance of, so they are using it as a storage room.
* The planet is now angry.

There isn't a soul that can resist the temptations of Chaos. Even a stone can be turned."
