Final Fantasy V/Earth Lithograph

Pyramids
At this point you can go north to Surgate castle, or further north to Karnak, but these towns have nothing new in them except updated gossip. Head west toward the Sand Tides; this time you must cross through a forest which is the last remnant of Moore Forest and there is a short cutscene where you pay your repects to Galuf at the Elder's Tree. When you enter the Sand Tides there is another short cutscene where you learn that the sand is no longer moving and it's now just plain desert. Continue west; if you keep going you eventually reach Moore Village, but there's nothing new but updated gossip here as well.

Enter the pyramid in the middle of the desert. This time there are two stone statues in front of the door to the pyramid. Check the door to start a battle with them.

When the battle the over, one of the pages from the Sealed Book floats to the door and burns up, thus unlocking the door.

It's a good idea to exit to the desert temporarily at this point to save and heal.

Pyramid interior
Before starting with the interior, you should be aware that many of the treasure chests here have monsters inside, so don't open them unprepared. Fighting these battles will take their toll on you MP, so if you intend to get all the treasure then it's a good idea to exit to heal occasionally. Enter the pyramid proper and take the westernmost passage north. There are three buttons at the end which control an array of spikes on the floor. Press the buttons to arrange a safe path over the spikes; it's the left and right not not the center to be specific. If you step on the spikes you get poisoned which is no problem since a few antidotes will fix it. If you have a Geomancer in your party you can just walk over the spike with no damage at all.

Continue south through an arch, then east and let yourself be swept down the sandfall (i.e. waterfall only with sand). Battle for the treasure at the bottom, then make your way north fighting the snakes on the way. Go up the stairs to the east side of the first floor. Follow the passage east and south, then turn north and go past the sandfall to the 2nd Floor. Find your way through the hidden passages west, fighting more snakes, and go back down to the first floor. Open the sarcophagus to start a battle with GrandMummy, with the Hex Ring as a reward. Go back as far as the sandfall, press the button to make it stop, then continue back to the entrance. Since you're near the beginning again it's probably a good time to exit temporarily to save.

This time take the next to westernmost passage north to the 2nd Floor. Go south through a doorway to trigger a trap where the doors close and snakes are released. Press the buttons to open the doors and continue south to the 3rd Floor. When you approach the treasure here more snakes are released, and all the chests have monsters to fight. Continue east and up the stairway, timing your movements so you can get all the way up before the stairs turn into a slide and you land on the poison spikes below. This isn't difficult, but remember where you are if you get a random battle mid-stairway.

The 4th floor is a large area with robots and a few snakes. Fight the mummies in the sarcophagus on the right to win a Thornlet. Go to the southwest corner, press the button there, fight the snakes which are released, then follow the passage on the west edge for treasure. Finally fight the mummies in the sarcophagus on the left to go on. There is a save point in the next room; from there continue to the 5th Floor.

You now start to encounter a creature called Zefa Zone in random battles. She doesn't attack directly but summons other monsters, then heals and buffs them. Defeat or disable her first, otherwise she'll make it difficult to get rid of the friend she invited.

Start by going left along a winding passage. Fight the snakes that are released and get the treasure in a small room on the 6th Floor. Go back to the entrance of the 5th Floor and go through the open sarcophagus, then follow the passage south. There are secret passages connected to this but ignore them for the moment.
