I just thought about something...

pirates didn't exist back then...

so it's not one of the jobs that existed in the older days of crimsonwood

Off topic-ish :
I think some people are overlooking NLC's time travelers. Foxxwit, Elpam, and Lukan. It's not impossible for pirates to be put into the story, especially with a pirate skill like Time Leap. Also, I don't know if they say when exactly Testenon (Kyrin's father/1st pirate-Buccaneer) existed, so he might just have been around during the early days of CWK.
