From the introduction:
A Rat Queens adventure for 3rd-level characters.
The evening started out with the greatest intentions. A few relaxed pints, lively conversation, and a good old-fashioned bar brawl. When the fisticuffs came, they were with a visiting noble named Sir Dandeleone of Lavender, a middling minor knight from a family of no consequence. All things being equal, it should have been a classic dust-up, forgotten by the morning.
But no. Things escalated.
