It is easy to forget how strong Grisia is when he cannot handle a sword, has terribly stamina, cant ride a horse and is is treated as little more than a cleric. But you really do not want to make him angry. Something Silent Eagle would agree with after his lover was held at sword point by the afore mentioned sun knight as he was tortured and ripped apart with ice magic.
When the twelve knights are all together and fighting as your enemy, your chances are so low that they won't even bother to mention how they beat you. Even if you're a dragon.
