Go West, Craftman (or, how to get to Idyllshire)

[Roth_Trailfinder]

ARR didn't lock you out of being able to get to specific overworld zones if you hadn't gotten far enough into the MSQ. A sufficiently determined (or adequately escorted) brand new player could get to Mor Dhona immediately following the intro quests if they wanted to.

But yes, the answer is that it isn't possible to get to Idyllshire until you advance the MSQ to the point where it takes you there.

Access to and from Limsa Lominsa, actually the whole La Noscea region, is locked away by the MSQ. If you start in Limsa you cannot leave La Noscea until you reach far enough in the MSQ. If you start in Gridania or Ul'dah you cannot go to any La Noscea area until you reach far enough in the MSQ.

The point in question is early on, when you are told to go visit the other two Heads of State and are finally given access to the airship travel system.

So, yes, not only was the "lock stuff behind MSQ" precedent set by ARR, so too was the "lock areas away behind MSQ" precedent.
