After a battle in Burenia, you are able to reach an elevator that takes you to the area of Ghavoran.
Reach the Next Area
You can't open the door on the left yet, so go to the right and use the Grapple Beam to pull the door open, and go through.
Jump and grab the blue ceiling and make your way up it until you are on the ledge above. Jump up onto the ledge on the left, and use the Grapple Beam to pull the box toward you. You can slide through the lower tunnel to reach a Total Recharge Station, but the path to the right is a dead end, so just climb up the blue wall if you used the Total Recharge Station. Then roll through the upper of the two tunnels. Jump onto the platform above the tunnels, then go through the door on the left.
Robot Chozo Soldier
Go to the left and another Robot Chozo Soldier will attack. Use the same strategies as with the previous one.
Reach the E.M.M.I. Zone
After the battle, go through the door on the left. Slide through the tunnel on the left, then go to the left side of the room and shoot upward to kill the flying creatures there, then use the Grapple Beam to reach the blue wall at the upper left. Climb along the blue wall to climb onto the ledge at the top of the room. Go to the upper right and go through the E.M.M.I. Zone Door.
Go Through the E.M.M.I. Zone
The E.M.M.I.s are still inactive, so you can explore the E.M.M.I. Zone freely. Jump onto the blue wall above you, and after it takes you upward, jump off onto the ledge at the top. Go to the right and you will see a door that you cannot open yet. Go downward from there, and you will see the inactive E.M.M.I. in the background. Slide through the tunnel on the left and follow the straightforward path from there, and you will find an E.M.M.I. Zone Door at the bottom right of the area. Go through it.
Get a Missile Tank
There is a large reddish creature here. Hit it once, and it will turn around and rise up on its back legs. Perform a Melee Counter when you see the flash, and shoot it to kill it. Then go through the door on the right. You will get a briefing, and can save the game. From the save room, go through door on the right.
Go to the right, and downward. Step on the platform on the left and it will rotate, preventing you from going back the way that you came. Roll through the tunnel on the left to reach the next room. Jump upward to grab the blue ceiling, and you will pull the machine downward. Slide through the tunnel on the right.
Kill the creatures in this room, then go to the right and slide through the tunnel there.
The flying creature in this room can create a toxic area beneath it. Go to the right and you can slide through the tunnel to stay safe from it. There is a Grapple Beam Block there that you can pull on to destroy, then roll into the tunnel to get the Missile Tank.
Get an Item Sphere
From the Missile Tank, you can ignore the path to the right for now, as it just leads to a dead end in Dairon, so go back through the tunnel on the left, and go to the left side of the room. Open the door there and go through.
Go to the left, then bomb the wall between you and the blue magnetic wall. It will open a tunnel. Slide through it and go down below. Kill the flying creature, then shoot the door with a missile, then open it and go through.
Shoot the item sphere in the statue's hands, then jump onto the item to get the Super Missile. It replaces your missiles, so you can use them the same way as before: hold R and press Y.
Get a Missile+ Tank
Go through the door on the right, then kill the flying creature, and use the Grapple Beam to reach the blue wall on the right. Climb up, use a bomb on the bomb block, then go to the left and shoot a missile at the door on the left, then open it and go through. There is a tunnel in the upper right of this room that you can reach by Speed Boosting, then using Shinespark. It leads to a Missile+ Tank.
Go to the Next Area
Go through the door on the left, use the Total Recharge Station if you wish, then climb up the blue wall and roll through the small tunnel at the top. Get into the upper tunnel and roll through it, then shoot a missile at the door on the right.
Shoot a charged shot at the flying creatures above you, then use the Grapple Beam to reach the blue ceiling. Go to the right and roll through the tunnel. Then get into the Morph Ball Launcher and drop a bomb to activate it. At the end, shoot a missile at the door on the right, then open it and go through.
There is another flying creature that creates a toxic area beneath it, so kill the swarm of small flying creatures with a charged shot, kill or avoid the two spider-like creatures, then hide under the platform if needed, to avoid it the toxic area. Then go to the right, pull open the Grapple Beam Door, and go through. You will reach a shuttle area. Step on the glowing panel in front of the shuttle to go to Elun.
