hmm...i hope we're not talking about the same cave. the 'ancient cave'? when i go in from the wastes, a door opens directly in front. straight down the path is a long bridge with sith statues under those shark tooth arches. bridge leads directly to a door with the black on red BoS space invaders logo over it. the map labels it the 'temple of shadow.' but it's locked. is the somewhere, anywhere else i can get to? (thanks for the tip on the key, btw. got it.)
