"A prehistoric civilization, so easily...

　I was stunned by the image the Demon Lord showed me.

　Lemcelia was a prehistoric civilization that boasted a glory far greater than that of today.
　However, that great civilization was destroyed by the clash of light and darkness, the clash of Nirvana and Naraku.

　Huge armors and dragons made of magic stand up to protect the world.
　However, they are blown away helplessly before Naraku and Nirvana.

　The floating continent disappeared without a trace, and some of the buildings crashed to the ground and became ruins.

I don't know everything. But the 600th terminal has been given far more knowledge and power than ordinary terminals like the Rakshasa that follow you. I have shown thee what I have learned through it.

　The black skull - the Demon Lord, Virgalodomus, tells us.

　At the same time, the images of the prehistoric civilization from its rise to its fall disappeared.

　The next thing I know, I see the original hall-like place in my vision.
　In the center of the room, there was a huge black altar.

"Have you realized the power of the Light and the Dark?
"...... Why did you show me this?
"The key to mastering power is image.

　"The key to mastering power is imagery," said the Demon Lord.

In the event that you're in a situation where you'd like to be able to use the power of your own mind, you can do so with a clearer, more powerful image.
"You mean my Darkness will be enhanced?
"Yes.

　The Demon King said.

I want you to activate the Kuro Altar with the power you have enhanced and refined.

　So we're back to what we were saying earlier.

The glory and prosperity of Lemurseria was due to the fact that it had understood and utilized the power of light and darkness to some extent. It's an immense power that cannot be compared to modern civilization or magic...

　The Demon King said as if to say.

You, too, have a part of that great power. Now activate the Kuro Altar, the greatest legacy of Lemurseria. To gain even more power.
"Lemcelia's legacy, huh?

　I look at the altar ahead.
　I can almost hear my heart thump, thump, thump.

　Something inside me is racing.

　Or... happy.

　As if in response to the altar.

　Oh, my God, this feeling.
　A rush that's not simple joy or excitement.

　Yes, it's... nostalgia.
　Looking at the altar inspires a strange kind of nostalgia.

"I am .......

　I walk up to the altar almost unconsciously.

"Mr. Chrom!

　And then someone hugged me from behind.

"...... Shea?
Please don't come any closer to the altar.

　Shea speaks as she hugs me from behind.

　Her voice was trembling.
　She was trembling, anxious.

"What's wrong, Shea?
I have a bad feeling about this. I have a bad feeling that that altar... will bring bad luck to Master Chrom.
"Bad luck. ......
There's no evidence. I just can't get rid of the bad feeling. ......

　I looked at the altar again.

　I looked again at the altar. ...... .......

　There was a low, roaring vibration sound that echoed intermittently.
　It was as if the altar itself was alive.

"......?

　If you look closely, you can see hollows at the bottom of the altar.

　There are four in all.
　Each one has a coat of arms carved into it.

　The four crests look like a design of spades, hearts, clovers and diamonds.

　The four crests glowed faintly...
　The altar has stopped vibrating.

I'm not sure if this is a good idea or not.

　The Demon Lord growled.

But it looks like the first stage of activation is complete. The feedback to you will occur eventually. But beyond that... we'll have to wait and see.
What are you talking about?
First, you've accomplished part of my wish. I'd like to thank you for that.

　A black blur spreads from the skull's eye sockets.
　It took on a form in midair.

　A ring with a sigil engraved on it...
