This is a Glacial Geek 8th Edition Warhammer 40,000 Batrep!

Azrael was directing the Predators into firing position when the call came through.
"Hail, Dark Angels, we have come to this planet to investigate the possible presence of Daemons. Why are you here?"
Azrael recognized the voice immediately, "If it were any of your business, Draigo, we would tell you."
"Is that you Azrael? Interesting how we manage to run into each other at interesting times."
"What do you want Draigo?"
"An answer to my question. Why are you here?"
"That is for us to know, not you."
"The directive of the Inquisition feels otherwise." Draigo said. Azrael glared across the city ruins and saw glimpses of large machines getting closer. Draigo continued, "And so do my Knight Titans."
Azrael cut the vox link and looked to his Techmarine, "Get these Predators ready for battle, now!"
Will the Dark Angels keep their secret, or will the Grey Knights beat their answers out of them? Watch and find out!
