*BIG FAT SPOILER ALERT*
*I MEAN IT*
I'm not sure if it's appropriate to ask for game help here, but I'm in Rentar Ihnro's fort west of Fort Remote, and I can't get any farther. I've gone down the stairs just by the room where the shades were made, and the friendly Vahnati are waiting by a gate for me to open it, but there's no where I can go that doesn't involve hitting an un-unlockable door. I've already picked up one crystal key that opened up some doors, but that's it. I've searched everywhere I can go besides those doors in the area, and am finding nothing.
I don't really need you to spell it out letter by letter, but if there's someone out there who could just give me a pointer in the right direction, that'd be muchly appreciated.
