4th Starting City-State in 1st Expansion
So if SE decided to add a 4th starting area in 1st expansion do you think it will be the City-State Sharlayan?
Currently Sharlayan is the 4th city-state in Eorzea that allows adventurers to enter the place lore wise and it is also home to the Circle of Knowing.
Sharlayan can be the place where 3 new Classes for 1st Expansion start out. (Limsa Lominsa 3rd Starting class is Musketeer since the Musketeer guild is already established in Limsa)
Starting Main Story will still mostly be the same but you will be more invovled with task from the Circle of Knowing in Sharlayan Starting Main Story similar to how Gridania Starting Story involves the God Quivers, Ul'dah involved the Sultan-sworn, and Lisma Lominsa involved the Yellow Jackets.
The Scion of the Seventh Dawn member players meet in Sharlayan Starting Story and introduce new players to the Scion will be Urianger Augurelt similar to how we have Thancred for Ul'dah, Y'shtola for Limsa Lominsa, and Yda and Papalymo for Gridania.
2.1 story has already set Sharlayan as a important story point due to what happened to the Circle of Knowing in 2.1 story. New Players most likely will meet the person mentioned by Minfilia in 2.1 during Sharlayan Starting Main Story before hitting level 15 Main Story quest for new characters.
