By the time he manages to return, Xendi's initial sweeps have cleared out all of the lesser guards, and killed one of the teams of horses. The other team has run their cart into the ditch, leaving the dragon and the three champions. As he arrives, she's swept back for a third pass, and lands, immediately within close-combat range of the man in robes, who doesn't look like he'll make it far. Of the three, only the archer sems to be relatively uninjured, apart from the group, and agile enough to dodge the worst of her breath attacks.
