All those playing "Touched by the Alien" please do not read on.
Ok, so I am hammering out the backstory for my game's plot but I've come into knot which I can't seem to untie properly and would need some help with it. The idea is that an Istvaanian Radical of the Ordo Xenos has a cooperation with a notorious xenophile arch-heretic. The Inquisitor wants to use the arch-heretic to cause chaos and strife and so ready the Calixis Sector for a greater horror, while the arch-heretic is just happy to be able to use the Inquisition to get advanced warnings and to direct them against his own rivals and enemies from time to time. So far the deal has worked very well for both parts.
Now as far as I have thought the two of them met when the Inquisitor was following the heretic on ships, but just as they engaged each other a xenos ship arrives to attack the two. Both ships are crippled, boarded and the crew taken captives by the xenos. And then its a stop. Something happens that allows for both the Inquisitor and heretic to walk away and with a new alliance between them.
Just what the hell happens? Any ideas that would make some sense?
