I just want to call attention to a potential poor interaction with oceans and quests before it happens. Long quests, particularly those for the Nomad credo, appear as if they would cross oceans. This might make the quests impossible or impractical to complete (i.e. "Leash a cow to this tree" when you can't bring a cow across the ocean, etc.). Also hermits may have difficulty in constructing ocean going vessels, which could prohibit them from accessing this content.
A solution would be to restrict quests to a single continent, except for special credos (like a sailor or navigator credo). Nomads don't cross oceans by definition.
Maybe it's already been addressed.
