Ydia the chanting goshawk bard has spotted the assassins in the royal audience stand and lets out loud chanting to warn everyone. No one in the audience knows this is meant to be a warning, but Sir Kiljaos the lion paladin knows and heads to the rescue, even though he's in a middle of a jousting match. Luckily Ydia's hollering and Sir Kiljaos's sudden moves seem to confuse the assassins, giving Sir Kiljaos some time to throw his lance at the assassins!
