Yamata Ruins

The Yamata Ruins are located beneath the city of Yamata.

Uzume's grave is located within the entrance to the ruins. The majority of the ruins cannot be reached without the Search Psynergy. Players must come here to acquire the Yellow Orb.

Walkthrough
Go back inside and check the red tablet. The sand will fall, letting you climb downwards. Move down and past the first room into the second one. Here, push the middle column into the left spot, the right one into the middle, and the left one into the right spot. Jump on the glyph and examine the tablet to lower the sand again.

Good, now jump back on the glyph. Go down and "Search" the glittering spot to find another glyph. To get the chest, you need to move column number 3 into the middle spot and column number 1 into the right spot. Do so to acquire the Thunder Crown, which is cursed. Go into the previous room and use the glyphs to continue. Head past the planks into the next room. The tablet here tells us that we'll be rewarded for all of this!

Keep going into another block room. Here push the right block to the right so you can get up to the next level and use Search to make another glyph appear. Go back down and move the right column to the left to line up with the up and down line, then move the middle column into the left slot and the last one into the remaining slot. Use the glyph now and examine the blue tablet to sink the sand some more. To get the Venus Djinn down there, go down to the columns. Now put the middle column into the right and then push the right column over to the left like we did before. Ride the glyphs now to grab the Venus Djinni Hemlock. Retreat to the previous room and go down the ladder here and use the stepping stones to reach the chest with the Cookie. Now go back up the ladder and use Grip to get over to the left exit. Examine the last tablet to sink the sand all the way. Now backtrack until you get to the gold tablet, where you can go even further down as you can see. Move through the door, jump on the glyph and watch the scene for the final orb.

Retreat back to the previous room and read the yellow tablet. This will cause the sand to sink further and lead the way to the Gaia Blade. Use Search to make the chest appear.

With the last orb, we can unlock the gate at the Endless Wall and make our ascent towards Apollo Sanctum, but we need the Umbra Gear to do much there.
