There is a story about the mountain outside of town.
It is said that the MONSTERS of legend, demons ~
were trapped beneath the Earth's crust after their
mischief had become too much for the humans to
deal with... But others, have a conspiratorial out--
look... That the MONSTERS did nothing wrong.

Some advice from the only monster who's your friend here.
Keep away from that one. She will tear you apart.
Like the last one to fall here.

Hello, human.
Sometimes, it is nice to unwind.
It is brutal out there in the cold.
But we're happy in here, so...
Take a little happiness with you.

Hey… remember when we used to mess around up by the mountain?
Feels kind of dumb now, thinking back...
like, none of us actually believed those stories...
I mean, come on. It was just a mountain.
...Until people started disappearing.

(Sampled from PeriTune.)

Hello.
I am Mushroom.

Could you take one of my spores

I wish to be free from this place.
Sankyuu.

How are you still alive?
Why did you come down here?
...
My name is Professor Alphys.
I don't know why I felt the need to introduce myself.

(Original composition by PeriTune.)

28. professor alphys

We each carry the wound of the abyss within us, and it is our refusal to look into it that gives it power.

29. praeconis fabrica (inferno intermission)

We once thought we had reached a new milestone.
Discovering this mountain's otherworldly properties.
Finding a way to save the people who turned.
...
Then he disappeared.

(Composition by Nobuo Uematsu)
