Ok I finallly get me a key to enter the battlefields. I'm exploring the area and come across some weird looking circular thing and when I mouse over it says "Entrance, Locked" Here is the pic, I took a SS so i could show you what I'm talking about for clarity purposes. It's small so it shouldnt hurt l;oading times.

Any idea on what this is and if so can you give me a hint, not a spoiler please, but a hint as to where or how I could unlock this.

thanks again for the help.

Nick
