First of all I wanna say that this thread is awesome, and super informative. Got me all pumped up to reroll a new character on the game and reread all the storyline.
And thank god I did, cuz now I can help out with this:

The LV. 2 Lominsan sidequest "Licensed to Reave" has you deliver a couple of spice sampler to both Coral Tower and the Bismarck.
When you deliver the sample to the Bismarck, Lyngsath, the guildmaster, says the following:
Lyngsath: A new sample from the Seventh Sage? Alright, let's 'ave a whiff of it, then.
Lyngsath: Hmmm... Ain't smelled nothin' like it afore. The note as came with it says it's a root what grows on Othard.
Lyngsath: Last I 'eard, Othard was under imperial rule. 'Ow the seven 'ells did Carvallain manage to get 'old o' this?
So Lyngsath confirms from the beginning that Othard is in fact under Imperial rule. Now how does Limsa get a hold of a lot of things from the East?
Carvallain: With the Admiral's blessing, we engage in a form of trade with Garlean ships. Everything we do, you may rest assured, is within the law.
As the sidequest summary states:
In completing the task, you have endeared yourself to Carvallain. He reveals to you his ambitions to grow rich as a privateer, attacking and looting Garlean ships in the Admiral's name.
