Here, use the nearby Bird Statue. Fi should point out the river of lava nearby. That is your only viable path for now, so go towards it. Launch your Hook Beetle and go down the river. At the wall near the end, turn around and you should see a crystal switch above the statue head – hit it.
Next, return to controlling Link. Hit the water plant above the river of lava with the Hook Beetle or something to make a platform, then ride it down the river. Kill the Fire Keese along the way.
Close to the end, look up to find a water plant on the other side of the fence. Hit it and, when near the end of the path (beside the short fence), jump across and get onto it. Start riding. As you do, there will be a lava waterfall at the other end – hit the crystal switch above it before you get there.
At the end of that path, jump onto the platform and use the wall switch to make another shortcut. Shoot the water plant nearby and start riding. As you do, a crystal switch will be above the statue you pass – hit it. Also, be sure to hit the nearby water plant, to make another riding platform.
At the end of the path, get onto the rising platform and, using your Hook Beetle, backtrack along the path and retrigger the switch. Afterwards, send the Hook Beetle into the alcove on the wall with the two statue heads whose lava flows you’ve been messing with to find a Silver Rupee.
Next, hit the water plant near Link, on the other side of the wall, and jump across onto the platform. Continue riding the platform. As you do, you’ll find some Cursed Spumes – guard with your shield, or Bomb them. At the end, Clawshot to the above ledge and, there, thrust your sword in Din’s marking.
In the alternate realm, you’ll find the Triforce of Power. Grab it to return to the real world. There, climb the nearby vinery and go along the path to a barred doorway. Pull down the wall switch nearby to clear the way. Go back to the entrance of this room from there, then return to the Mini-Boss room.
Rearranging the Rooms
Back here, go to the control panel and start moving each room in a counterclockwise manner until the blue Triforce room is due north of you, with the top-left and central-left rooms making a path from you (the center) to the blue Triforce room.
After the rooms have settled, go into the western room, which should be the Fire Room. Go north and through the shortcuts, then exit via the north. You’ll be back at the Entrance Room; from here, go along the path and through the other doorway to reach the Triforce of Wisdom room.
