sorry in advanced for my vagueness

I was wondering if there was any way I could gain access to this fort. Its really early in the game. After you leave the monestary, the first area, and travel around in the sand, you come out onto grass and on your right there is a fort looking building. I was wondering how I could get in there and explore.

hope that description is enough. thanks.

Can't get in there from out here, the first time. Gotta get zapped into the house later in the game.

You will be able to get there using the portal in the Umpani areas, and after that you will be able to open the door from the inside.

thanks lots. I don't mind the spoilers at all. I would have killed myself thinking I was missing something.
