Rothlyt Sound - where is it really?

[Kyan]

Hi voidsent friends in the localisation team!

Limsa Lominsa, a nation founded by pirates, has caught me by surprise - their navigation and map reading skills are either really lacking, or there is something majorly wrong with the Eorzean maps! I am talking about the Rothlyt Sound - which is located on the opposite side of Eorzea.

First, there are the monsters, such as the Rothlyt Pelican, located around Aleport in La Noscea. There are also Rothlyt Oysters fished around La Noscea, as well. Thirdly, there is also this strange comment about wind coming down from the Rothlyt Sound to dry harvests at the Red Rooster Stead:

Before grain can be milled into flour, it must be dried. During the Sixth Astral Era, we would dry our wheat in the dry salt winds that came down the Rothlyt Sound. The past five years, however, those winds have been warm and wet. Not only does it prevent the grain from drying properly, but it breeds mold. For this reason, we have opted to abandon the traditional methods of drying for a new technique using the cores from wind sprites. Drying is much quicker and more efficient, the only drawback being that none of us here at the Grey Fleet are competent enough with a blade to procure the cores ourselves. So, we must ask the aid of adventurers.

Does this leve text mean the Straight of Merlthor or the Indigo Deep? They would seem more likely to me?
Thank you for solving this geographical challenge!
