The Temple of Balance
Use the top-centre Serpent Gate to go to the Temple of Balance in Sunrise Isle.
Gather the four glass serpents from the corners of the room and put each on scale matching red with blue. The three artifacts of Order and the three artifacts of Chaos will appear on the pedestals. Take them with you before you leave.
Place the six artifacts on the pedestals of the appropriate shrine: the Chain with Ethicality, the Torch with Tolerance, the dagger with Enthusiasm, the Rose with Discipline, the Abacus with Emotion, and the Heart with Logic. When you have placed the last item on the pedestal, a book will appear. Take it and return to the temple.
Stand between the two pillars and read the book. A bridge of fire will appear. Repeat this again between the next two pillars and another bridge of fire will appear. Cross the bridge and enter the Shrine of Balance.
Go to the left and take the key from the bag. Go all the way to the right and open the chest with the key. Take a serpent candle and put it on the blue pedestal on the far west side. Take the Ice Diamond and a chunk of ice. Put the block of ice on the red pedestal on the far east side. Take the Fire Ruby and put the two diamonds on the pedestals before the big brass door to continue.
Climb the stairs to the left and push both buttons. Walk through the illusionary wall under the stairs and push the button on the wall. Step on the right teleport. Press the button in the room with the abacus and then go on the left teleport. Climb the stairs and take the key from the chest. Cast Telekinesis on the button in the room with the torch. Descend the stairs and press the button in the room with the heart. Take the teleport back to the abacus room and open the door with the key. Descend the stairs and take the Key of Fire from the brass treasure chest. Return to the room with the Heart and open the door with the Key of Fire. Take the Key of Ice from the chest and two cubes of ice. Return to the room with the dagger and use the Key of Ice to open the door. Take two cubes of fire. Put the four cubes on the black pedestal in front of the big brass doors. Climb up the steps and read the scroll. Equip the Serpent Earrings, Armor, Crown, and Staff and make sure you have all three blackrock serpents. Step on the teleport.
Ascend the stairs and place the Serpent Staff, Armor, and Crown on the table to become the Great Heirophant.
Walk through the doors and defeat the Order Serpent's minions who are trying to stop you from restoring balance.
Place the three blackrock serpents in their proper slots to open the Wall of Lights.
Place the two serpent eyes on the altar in front of the serpent.
Destroy the serpent with the Ophidian Sword to restore balance to Serpent Isle.
The Silver Seed
Arrival
Use the Amulet of Balance any Serpent Gate to travel back in time. You will appear in a garrison of the forces of Order, called Serpent Fang.
Go to the north chamber and speak with Isstanar, Commander of the Garrison. He will give you a magic keyring upon which you can put all your keys without taking up extra space. He will also tell you where you are and what is happening.
Talk to the other people in the garrison to learn more information.
Go to the south end of the garrison and use the winch to open the gates.
Around the castle are four areas, each containing an orb and a magic treasure. In front of three of the areas a monk will appear to give you some clues about the area behind them. These areas can be done in any order.
The Silver Seed
After you have collected all four orbs, return to the garrison.
Go to the north end of the first basement, just before the stairs to the library and push the button behind the lantern.
Go west and descend the stairs behind the cask.
Put the four orbs on the four pedestals at the end of the tunnel. You know the orb is on the right pedestal if it turns black.
Go up and grab the Silver Seed. The three monks will appear and attack you. Take the keys off their bodies.
Use the keys to open the doors ahead to reach the end of the cave.
Karnax will appear and talk to you when you leave the cave.
Put the seed into the black hole in the middle of the glade and watch the Tree of Balance grow.
Use the Amulet of Balance on the serpent gate in the middle of the garrison to return to your own time.
