I seem to be stuck at the ominous black gate in the black cove. I've found and pressed the button behind the picture in the 'office' but the door is still locked. I've also tried the lever in the same room but I wasn't able to spot any effect... the gate is still locked.
Is there something else I need to do to open the gate? If I'm not able to get the door open, does it gate my progress in the game?
I'd appreciate any help.
