Echo

THIS PAGE CONTAINS SPOILERS

Summary
As current Lore stands, the Ancients whom Slugcat meets are the echoes of Rain World's previous civilized race; forever stuck between transcendence and the Great Cycle. Six Ancients can be met throughout Slugcat's journey. Their names are as follows:
 * Nineteen Spades, Endless Reflection, found at the top of the center chimney in the Chimney Canopy
 * Six Grains Of Gravel, Mountains Abound, found in the area between Five Pebbles and The Wall
 * Four Needles Under Plentiful Leaves, found in a grotto under the eastern entrance to the Shaded Citadel
 * A Bell, Eighteen Amber Beads, found in the Farm Arrays high above a patch of Worm Grass, near the entrance from the Outskirts
 * Two Sprouts, Twelve Brackets, found in the Subterranean region as one enters from the Farm Arrays, in a cave to the right.
 * Droplets Upon Five Large Droplets, found high up in the Sky Islands, above the orange lizard infested tunnel near the gate to the Farm Arrays

Gameplay
Ancients are non-hostile and, upon finding one, it will reveal certain aspects of the game's backstory and then teleport Slugcat back to his previous shelter. This also takes Slugcat to the highest karma tier. The Ancients appear to have set spawn-points, but are not always there. If one is near, you can tell by the environmental changes. First, the area will grow darker. As you get closer, golden flecks will start raining down and everything will take on a distorted appearance. No enemies will appear during this time usually but if one does appear it falls limp to the ground.

Nineteen Spades Endless Reflections
Behold this empty husk of a land...

Populated only by storms, ruins and abominations. It wasn't always thus.

I was once the Count of 2 living blocks, esteemed by my peers. I had progeny!

From within my vessel of flesh, I would perch upon this spot to observe the rising of the sun.

Corporeal matters seem so distant now. Most have forgotten this place, but I remain.

Perhaps I reminisce because I cannot go. Perhaps I cannot go because memory traps me here.

Six Grains Of Gravel, Mountains Abound
We can feel your presence, little creature.

Your attunement has become... much closer to ours.

The mark you received is an unimaginable gift.

The struggle, the cycles...

It can all fade, like a morning mist beneath the glory of the sun.

We found a way.

Four Needles under Plentiful Leaves
You have no name.

I once had! I was embalmed, adorned, readied for the journey.

So proud. There was jubilation! My name was sung, loud and clear.

Did they know? That I didn't quite leave, didn't quite stay?

Should I be ashamed? That I linger here, where my memories are kept?

Should I be ashamed that I now envy your flesh prison?

A Bell, Eighteen Amber Beads
Strange...

Something still draws me here. Even after all this time.

The weather is so different now, but the fields...

I do not need eyes to know that the grasses still sway gently in the winds.

To have grasped at the boundless infinites of the cosmic void...

Yet here I am contemplating these same fields as I once did, talking to some sort of rodent.

Two Sprouts, Twelve Brackets
A little beast!

But not as dim as the rest, perhaps?

So down into the depths you go as many others before you, drawn to the void again and again, an endless drip drip drip.

Much like these tunnels and caves that amuse me so. The bones of forgotten civilizations, heaped like so many sticks.

Did they dig too deep, or not deep enough?

Fools. We were right to drill straight through them!

Droplets Upon Five Large Droplets
Do you hear it, little one?

The buzzing in the air?

The endless chatter of a thousand thousand voices, long dead?

They are gone, and yet they speak. Neither here nor there.

Does that seem familiar? Yes, it is quite amusing for a being in my predicament!

Trivia (spoilers)

 * It is possible to complete the game without going to Five Pebbles by talking to each of the Echoes, who bring your karma limit up and max it out.
 * Every Echo/Ancient exists in their form because they were too arrogant or egotistical for the void fluid to completely destroy them
 * If you look closely at the graffiti art in five pebbles (section where you get to the wall), you can see what the ancients had looked like. Their head shape stayed the same though.
