Rob was out of the Pentagram before we could stop him.
Despite the monstrosity, despite Farmer's warning never to cross a power threshold, Rob threw himself through it, a crazed smile on his face, longing in his eyes - looks that turned to anguish as he passed through.
The next moment Rob's contorted body thudded to the floor, beyond all protection, motionless, and as far as I could tell, not breathing.
It's a blessing, I suppose, that the pentagram's potency remained strong, because the effects of passing through it are unpredictable.
A blessing because Malkaz lowered his head to Rob's face.
