Yamata Ruins (2)

Return to the red tablet and examine it to lower the sand, allowing descent.

In the second room, rearrange the columns: middle to left, right to middle, left to right. Jump on the glyph and examine the tablet to lower the sand further.

Jump on the glyph again, go down, and "Search" the glittering spot for another glyph.

To get the chest, move column 3 to the middle and column 1 to the right. This yields the cursed [Thunder Crown].

Return to the previous room and use the glyphs to proceed. Go past the planks into the next room.

Continue into another block room. Push the right block to the right to access the upper level. Use "Search" to reveal another glyph.

Go back down. Move the right column to the left to align with the up/down line. Move the middle column to the left slot, and the last column into the remaining slot. Use the glyph and examine the blue tablet to lower the sand.

To obtain the Venus Djinn, go down to the columns. Move the middle column to the right, then push the right column to the left. Ride the glyphs to acquire the Venus Djinn [Hemlock].

Retreat to the previous room, go down the ladder, and use the stepping stones to reach a chest containing the [Cookie].

Go back up the ladder and use "Grab" to reach the left exit. Examine the final tablet to lower the sand completely.

Backtrack to the gold tablet and use the gold orb to lower the sand even further.

Down here, use "Grip" and "Search" as needed to find the [Gaia Blade].

With the last orb, unlock the gate at the Endless Wall and proceed towards Apollo Sanctum. The next objective is to acquire the Umbra Gear. Sail east of Yamata to find a beach and a cave leading to the Umbra Gear.
