The party may find text written in Islarhi, the ancient druidic script. Around The Haile, it's not unknown (many locations are referred to by their Islarhi name), but nobody is really fluent in it.
A Noble or Minstrel can spend time translating the text. If they do this during travel, they do this in the evening and can't contribute to setting up camp (much like the Hunter's hunting ability).
When a Noble or Minstrel studies, they roll INT + INT as their Knowledge ability. On an 8+, they make progress; some bit of information is revealed. After a certain number of successful rolls, you may choose to reveal the information to them.
