We should play the encounter with actual demons for the sanity-bending event that it is. I tried to make sure I was doing the Bloodletters right and I think I will take a casualty or two here.

What [@Bright_Ops] did gave us some much-needed challenge to the first scene. Suddenly, taking out those officers...well, they now discover that in desperation, adherents to the Dark Gods can sell themselves quickly, sell others out as sacrifices and bring much more potent foes to the battlefield. This should make all future encounters uneasy. And yeah, there is no Ordo Malleus and Space Marines, particularly these Space Marines, are not immune.
