Two Players, Two Differnt Starting Towns

[Anova]

The story allows you to freely travel between cities starting at around lvl14-lvl15 (depending on how early you rush it). At that point, the individual city quests end and all players begin following the same storyline. For reference, the story quests are shown by a special quest icon that looks like a flame. Also, try not to ignore quests given by your class' guildmaster as those are class quests and they give useful equipment and abilities that will help you level.

If you want to meet before 15,you can walk to Gridania (-north> central thanalan -east> eastern thanalan -ne> south shroud -n> central shroud-n> gridania) or reverse it to travel from Gridania to Ul'dah (be aware there are aggressive mobs in eastern thanalan and south shroud you will want to avoid). You will not be able to run all the story quest content together though, and the game may require you to separate the party for instances, but you will be able to play the fates and many quests with your spouse. Unfortunately, not all of the quests in your respective regions will be available to both of you. By default, you will have some lvl1-15 quest lines in ul'dah your spouse in Gridania will not have access to and vice-versa. Frankly, there is not a lot of incentive to go to other cities until level 15.

You can still party together for behests starting from level 10 to help speed up the experience. it is a nice chunk of experience and will speed up your progress until you unlock airship travel.
