"Some of them, definitely, others, not so much. It's hard to explain simply because we don't know about them ourselves," Mac replied with a long sigh, pointing to the screens. His Ghost bobbed a little nod, and the Warlock got up, walking around the cockpit towards a back area near the mess, clearly a place of research. Strange artifacts littered a workbench, old books tucked into cubbyholes. Reaching out for a stack of papers and leafing through them, he laid out several showing excellent sketches of Vex, Fallen, Cabal, and other lesser creatures.

"Cabal and Fallen definitely do, they're humanoid carbon-based, not much different from any of us. Vex though," he tapped on a few breakdown images of the constructs.

"They're nothing like anything we've encountered before. We thought they were just artificial life forms, metal constructs, but it turns out they're far, far more complex. Biological artificial metal constructs. Metal and organic, but not like cyborgs. Down to the last cell, it's a little of both. They don't have brains...their thinking parts are fluid. And they don't communicate the way you and I do. they're a hive mind. While physically they're not the strongest, mentally they're impossible to fully comprehend."
