So I decided to take the plunge and actually play the Inquisition expansion.
>Play Grey Knights
>ok, cool, we get to bash daemons and shit
>take mission to initiate an assault on a daemon-infested feral world
>hey cool, daemons and killer fauna, this'll be a breeze
>mission requirements: need to recruit an Inquisitor
>hey what? fine fine, let's take that veteran-looking gentleman over there
>hey, cool, he's a bro
>requirements to recruit: complete a mini-mission by his rogue trader contacts
>suddenly, change control to rogue trader
>awwwwwyeah
>fly around, investigate and trade for artefacts
>hm, artefacts seem odd, nah, probably will be for confiscation
>100 turns later
>crap crap crap being chased by daemons all over the bulkhead
>turns out artefacts were daemon magnets
>complete mission with only 3 crew left
>suddenly, switch back to GK for no reason
>get told that your bro mite be Radical
>meh, he has cool toys, dismiss allegations
>get new mission: stealthily investigate a cult that's sending chaos forces into the feral world
>suddenly, i'm now an acolyte
>darkheresymode
>sure feels heretical, aiding and manipulating these cultists
>mission success
>return to GK
>get asked by system: are you SUUUUUURE you want to recruit this bro?
>yeah yeah
>SUDDENLY, EVERYONE LOOKS AT ME FUNNY
>SUDDENLY, BRANDED HERETIC
>spend last few turns escaping from Terra
>YOU PLANNED THIS ALL ALONG, DAMN AI
