They really could just include Stormblood in the free trial...

But yea, it is for the "Starter Edition", which should be about 10€/$ but does stop the free trial forcing into the monthly subscription cost... It's mostly meant to remove all the restrictions of the Free Trial, without getting any of the content past HW until you reach that point in the game, but I guess for now it does come with free Stormblood.
