The Dragons' Last Breath

You've found what seems to be a piece of a treasure map while exploring the remains of a dragon skeleton! There's inconspicuous writing on the back of the parchment.

Perhaps there are more pieces like this one in similar places. If you find all of them, you can combine them into a reconstructed treasure map!

Find all of the treasure map pieces!

You've found the 4 treasure map pieces, but they're hard to read in their current state.

Use them to craft a reconstructed treasure map!

You've reconstructed the treasure map, and you can make out its details now. You can see a lake with an island, a river, an obelisk, and parts of a large skeleton. The full writing on the back now reads:

Mae's Memoir:

The first day of yearwake is unlike the rest

The peaks lay quiet, licking yearfall's wounds

As the sunlight sets in the faraway west

On fields where sleeping buds awoke to blooms

Polaris' Memoir:

I'm a shining star, drifting high up in the sky

To find your path, you must look to me only

Gazing down at the world, it's hard to deny

Having no one at my side makes my spirit lonely

Orpheus' Memoir:

Once born a wanderer, I sought incandescence and bliss

Now I'm frozen in time, my body cast in chains

Accustomed to a sea of shadow, deep in the abyss

My eyes hurt in the brightness, so no light may remain

Ony's' Memoir:

I fly so high, I may never come down

I dance on the sun, whole body ablaze

My cup's always full, I'd drink till I drown

In liquid light and limerence, until I feel dazed

You've followed the map to a hidden temple behind a waterfall, but its treasure lies behind a locked door.

Lights above the door indicate that it can be opened by a mechanism. Figure out how to open the door to obtain the treasure!
