Using the PC’s rules for demi-human class creation, it’s possible to create a class with a maximum level of 8. Strongholds typically kick in at level 9. The PC text says, “At particular milestones, all classes become eligible to build strongholds and attract followers.” Does that mean a class with max level 8 gets a stronghold at that level? Or must acquire their own by other means, and doesn’t attract followers at all?
One possible solution, so that they don’t get strongholds earlier than everyone else, is to require they gain a specific amount of xp beyond 8th level before they get a stronghold. But I’m not sure what the original intent was.
