With the elementals watching over Gridania, I have no clue how one would stage a successful invasion of the Shroud. However, Limsa is in a position to completely devastate Ul'dah. Much of their trade does come from overseas (keep in mind that Eorzea isn't the entire world, and the only thing left to the East is the Empire). Frankly, the Maelstrom wouldn't even be required to put boots on the ground, assuming the goal was to destroy rather than capture. All that would be needed is to set up a naval blockade, then tell the privateers that Ul'dahn settlements are fair game. Then sit back and watch as port after port burns to the ground. Sure, the Ul'dahn army would slaughter wave after wave of pirates. But that sort of wealth is too great to pass up, and eventually they would succumb to the sheer number of crews from around the globe looking to grab a piece of that sweet desert gold.Â
Not to mention that Limsans are experts in powder weapons. Ancient weapons and hokey religions are no match for a good musket.
