Hi - When you enter or re-enter a Ruined Outpost, do follow the Ancient Ruins text on page 12 or generate an encounter on page 15? Thanks again!
You can play it both ways - but the intention was that a ruined outpost does not contain an orb (on the assumption it was taken in the past) - but it could have an encounter, and you need to check each time you visit the ruined outpost.
