It is important to note i feel that, unless I'm misremembering, the warpstorm that stopping "safe" travel to and from the planet has been there since before even the first chapter. So the Assassins would have needed to be on planet prior to Tide taking so much as his first steps in this world, which seems to be confirmed during this chapter. So their reason for being here would be something not directly caused by Tide. Considering that the chaos cults on planet were caught entirely unaware by Tide, and the only hints they've gotten from Daemons at all has seemed to be mockery(directed at the cultists) and the repitition of the number four, it seems unlikely to me that any diviner would have been able to predict Tides appearance either. I am almost less worried about the assassin team themselves, and more what would have warranted them being here. If the speculation of this being a "Execution Force" is correct, and that is as big deal as posters in this thread more familiar with 40k then me claim it is, what kind of threat would prompt a High Lord(who from my understanding are typically extremely self serving, as one would expect from most any kind of nobility) to send them here to a usually ignored corner of the galaxy?
I'm starting to wonder if the presence of Orkz, Chaos, Tyrranids, and perhaps even Tide is less a matter of chance and more of somethings design.
