Bran drew his sword as well and got into a ready stance, but held off attacking for a space. "I don't know who you are," he called across the courtyard, "but I have to warn you, if you're threatening innocents, I won't hesitate to kill you to protect them. I'll give you once chance to surrender. If I were you, I'd take it." He didn't really expect the half-dragon to listen, but that didn't matter--all he was really doing was stalling while he reached out for the power of his god to bolster his energy. The day's fighting had been taking its toll, and he'd need to be at full strength again to stand a chance. Even so, there was always a chance his opponent would reconsider.
