I'm having doubts, that a pawn needs to be rented with 2-Star Knowledge before the 3rd Star triggers. But I can't assure it's wrong.

The Beach was often a place, where pawns gained their 3rd Star Knowledge. (sometimes found in comments) The Pawns should then say: "I sense something nearby..... A ... Bird perhaps?" Not sure if a Griffin is meant but there is a Cockatrice Post Game western of the Castle.

My 3rd Star has been triggered walking the Miasmic Haunt's Waters during nighttime, (Debilitations at day, nothing at Night) stating the Fairyflies or whatever protecting you?

This leads me to believe you need to trigger Area Knowledge like Beastiary: Comments for specific places only gives the 3rd Star. However I also heard the "I learned of this Area" from Pawns by visiting places like the Beast Cave or Nightcall Crevasse, but all were still stuck with the 2nd Star.

Hope my Experiences brought some light into your Question! :D
