The Dark Angels cautiously moved into the courtyard of the castle. Atlas had strangely understood the sign outside, but this world was not recorded in starcharts. In fact, he wasn't quite sure what planet they were on to begin with. It was certainly different from the battleground the tactical display had claimed they were approaching; and there certainly were no castles there.
Battle Brother Lurkis approached the door, bolter at the ready. Though this place was unfamiliar, there was still a chance for Orks to be inside.
The squad moved in, one at a time, and began to move through the hallways.
A short while later, Atlas found a large door; to where, he was not sure. His men stacked behind him, and waited anxiously as he turned the corner.
They walked into a massive, dull gray room; what appeared to be a coliseum or arena of some sort. At the other side was the true eye-grabber: a large black... thing; a mass of what appeared to be flesh. Atlas signaled to it, and Brother Uther went towards it, scanning it as closely as he dared.
"It was alive," Uther shouted. "at some point at least. Definitely not Ork. Never seen anything quite like it, actually."
Atlas and the other Angels moved closer. There were wounds and scabs all across its remains, some of them appearing half-healed.
"Soldiers, spread out." Atlas commanded. "Whatever this thing was, somebody killed it. That means we're not alone. I want two man groups in every corner of this building; we are going to find whatever brought this down. If it's human, try to establish contact; anything else I want dead."
