The room was pitch black. Twilight used her horn to produce a small amount of light. The building seemed small, doors on any wall.
They tried the door to their right. The room was filled with ancient books and scrolls. Twilight opened a book titled 'Time Paradoxes and How to Fix Them by Doctor Whooves'. As soon as she did, it collapsed into dust. She tried another, 'Dungeons and How to Escape Them by Dusty Tomes' This one too, collapsed.
They opened a scroll. Twilight read it aloud: "In nomine invocatoris, si non satisfactus es, cave. De vermis non absolvo follen legendum fatum et eum versus-" Twilight stopped. She understood just before finishing that these were words of death and should therefore not be spoken.
She looked at yet another scroll.
She read it. "Cthulu fhtag-" She knew this was to summon something, so she stopped again.
They exited the room.
They went left. It had an archaic record player. Nothing close to what Equestria used to have.
A record was in it. They decided not to play it. Also in the room was a statue of a human. This building has to be Human-era!
"What is that statue of?" Ace inquired.
"I think it's a human..." Twilight responded.
"I thought those were only myth!" Ace asserted.
"It's unknown if they were real." Twilight answered again.
"Oh..."
Twilight and Ace trotted outside the room and cantered forward into the foremost door. It was a double door, either side decorated with human statues holding spears that towered over the doors. Twilight used her horn to open the doors. The other side of the doors was humongous. The ceiling was extremely high, the walls ornate. Two suits of human armor were on either side of the foremost wall. Sitting in a towering throne was Discord, unfrozen.
"So you've come, Twilight Sparkle." Discord indicated.
