Alright, so I'm at Hyrule Castle... I go inside and take a right in the main courtyard, kill all the dudes blah blah, open the gate on the far right and beat the big orc dude on the boar. Myes? Myes. I think I got a key from there and used it to get into the Castle. So in I go.
After killing all the lizard dudes that ambush you, I used the double hookshot to get up to the chest that appears, and up to the central balchony to enter the door. Behind that door is a knight waiting to fight you (I love those fights so much btw, should've had them roaming in Hyrule Field or something =D). I beat that guy and used the lantern to light two torches on the west side of the room, to raise some flooring in the center. But I haven't raised all floor panels and cannot seem to get up onto the required ledge to obtain the newly appearing chest... So I leave the main castle after scoping it out, back into the courtyard to see if I missed anything.
Anyway I head back and go the west side of the courtyard, through the door, I get past the guys on the towers using the boar to break through the wooden barricades and get to the part with the large Triforce symbol on the floor, and 6 large pillars with fans on the top.
Thinking back to the first temple, I'm thinking I should use the Gale Boomerang on all the fans in order to make the gate at the far end open. I can't seem to find the right order of the fans to lock onto though... After trying for a while I give up and turn into wolf Link to find a small patch of dirt that you can dig through. It took me through to the graveyard at the back. I got the clues from the two large gravestones inscriptions and went wolf link to reveal the rock that's hiding a switch next to one of the trees (bunch of dead guys circled around it that you can only see with your senses on). So I use a bomb to blow up the rock and flick the switch to open up a gate in that vacinity, there's a torch there that I light up and the camera temporarily pans towards the main castle... I'm guessing that also raises another floor panel? But when I go back there everything is reset, the flooring and the torches are lowered and put out... And still I can't get past those six pillars with the fans on them (which is seeming necessary).
I also saw in the graveyard, two of those statues you can possess with the Rod in order to move them about (they're behind a locked gate and it appears there's some sort of tableture on the far wall in the room they are in)... So is that useful for something?
I really want to get on with the game, and have been looking around for ages, it's probably something incredibly obvious I overlooked, but how do I get Link up to the chest in the Knight-Battle room on the second floor of the Castle?
To anyone that's reading this part, you get a cookie for putting up with such a long passage.
