No, it's not Cao Pi's birthday, but Rosinante doesn't offer up that it's his. It's not out of some desire for nobody to know, he just doesn't want anyone acting like he deserves something for being present on a date. It's not like he's even alive for it. Good excuse to drink, though.

"I got a compass," he offers instead, and retrieves it from a pocket and sets it on the bar. "Points to the bonfire from wherever I am. We've been here a year, you know," he offers as a possible explanation. Why the spirits care or would mark such an anniversary, he's not sure.
