Lore

The crest is that of the king's Feast Master. It's covered with a greasy film that won't come off no matter how much you clean it.

"They say that, before being placed in his current position, the king's Feast Master was a murderer scheduled for the gallows. I believe it, for there are none who love the artistry of slaughter more than he."
