After you've followed the path to the northeast from Vale, you'll enter a cave. You enter an area with a waterfall trough it. Go to the broken bridge and jump on the stump and follow your way. Climb the ladder and use (Move) to move the pillar into the hole. Go on and climb the ladder. Now, go to the left again and try to move the stump. It's trapped into the ivy, darn! Don't worry, Ivan to the rescue! He couldn't save Hammet, since Lunpa was locked. He decided to help you and Garet, because he knew what you was doing, by reading your mind, remember? He will use
(Whirlwind) to blow the leaves away. Now you should be able to move the stump to the left. Enter the Goma Cave!
Be sure you are healty enough, because you will battle some ghosts, bat and other monsters, including the Mars Djinni Forge! Head north, and you'll ecounter a landslide. Go to the left and back to the south again. Go up the stairs and enter the stairs leading deeper into the cave.
Now, walk completely to the right until you see a pillar and a man. The man says a Djinni whacked him and fled again. Move the pillar first to the right and then to the north until you can't go further. Go back from where you came, to the door! But before entering the door, go to the south and you'll see a passage. Jump over the water and follow the path.
Go to the left and jump on the stump and follow your way to the north. Go up the stairs and you come in the same area where you was before back. What you have to do, is the to move the 2nd stump to the bottom of the cave. First, use move on the 1st stump to get it to the right and then you have a free way to move the let the 2nd stump fall down. Use Move again. Go back and in order to get the treasure chest, move the 1st stump again to the left. There is a psycrystal in it. Go back to stairs and you are now able to move to the east. Follow your way to the stairs leading one floor higher again.
You are now near Forge, so jump over the pillar and save, because this Fire Djinni could ran away from it's battle to test you. Battle him, by using Flint against him or just use your psynergy. Remember, he has a great resistance to fire, so you should let Garet attack him with his sword. After you got Forge, the man will dissapear. Enter the stairs at the north and follow your way out, by moving the stump in the water. You can now head to the north and exit the Goma Cave.
Once you've exit the Goma Cave, you'll immediatly encounter Bilibin, so enter it. You see a tree, but it's man actually (you can read his minds with the mindread of Ivan, remember?)! Now it's time to heal yourself, so go to the Inn. If you head to the sanctum, go to the south and walk all the way to the west on the gate of Bilibin. You'll see some leaves, so use your (Whirlwind) to blow the vines away and enter a secret cave. You are now in the underground, the secret storage of Lord McCoy, who is ruling this town. Go to the right and move the statue away. You'll meet the Jupiter Djinni Gust, you don't need to battle him.
If you go to to the northern edge of the town, you'll go to the palace of Lord McCoy. He's troubled, because there's something getting wrong: his lumberjacks doesn't return for his palace of his wife. At the left, you'll see a nut hanging in a tree, so why don't you grab it with (Catch)? Talk to the soldier at the left and he will guide you into the palace. It's one straight way to meet McCoy. After a lot of talking, McCoy won't let you to go to Kolima Forest, because he doesn't want you to turn into a tree. He takes the key of the Bilibin Bloccade up ahead away and asks you to go away again. The soldier felt sorry for you but whispers that you don't need a key at all, to go to Kolima Forest.
Now, take your time by exploring the castle, and you'll find some coins here and there. Exit the palace and then exit the town.
