So the Kill Team has just discovered a fully functioning STC, it will quickly become apparent that it has been tainted by Xenos. There is a group of AdMEch on the way with the firm intention of destroying the device that they see as an Alien Heresy, meanwhile the Deathwatch have initital orders to secure the find (although at this stage their superiors don't know what it is).
Question is where do I go from here. Myself and my brother were talking about this and we came to the conclusion that a fully working STC even if untainted could destroy the Imperium or usher in a new Golden era.
But thoughts are welcome.
