As they came back into the lobby, they found that the door Ignis and Prompto had been working on was opened, and the pair was nowhere to be found. Deciding to go through to try and locate them, they entered what appeared to be an auditorium - one with a large number of purple chairs lined up on either side of the center aisle. They didn't seem to be anywhere in sight here, either.

"Iggy?" Gladio called out. "Prompto?"

They walked towards the stage, and around the left side appeared to be a passageway leading around the back. As they came around the corner, they stopped at a fork - the path on the left led to a set of stairs, and the door at the top was opened. To the right was another door, also open.

Gladio checked the stairs, though was quick to turn around after he glanced into the room beyond. "Nothing here. Just seems to be a projection room."

They went through the door, following a set of stone stairs that would spiral upward. As they came across the room at the top, Nyxia was relieved to see the others as they appeared to be hovering over an array of monitors. "There you are," she sighed in relief.

"We saw you guys!" Prompto said almost excitedly. "We saw you here." He pointed at one of the screens on the right side of the table, and she was quick to recognize it as the hidden passageway behind the bookshelf.

"Yeah, we found an elevator, but we couldn't figure out the stupid puzzle," she said.

"The icons must be placed diagonally. It's not as simple as it sounds, though." Ignis said. "And did you find a purse while you were down there?"

"I did, now that you mention it. Why?"

Ignis pushed a button beneath the monitor, showing what appeared to be a recording of a girl dropping the familiar pouch as she was running through the corridor.

"That's Beth," Nyxia murmured thoughtfully. "I wonder what happened."

Ignis pulled himself out of the chair, then gestured towards something on the ground by the window. "We found something interesting, as well."

"The same girl's ghost was in that pot. She said the markings on them are important." Well, that solved the mystery of what happened to Beth Nelson.

"Oh! The book I found... it's in the library, but it says they resemble elements. There's a very specific combination in how the pots and lids go together. Each spirit is bound to a certain element."

"Ah, of course," Ignis said thoughtfully. "Then, the one bound to water must have been what attacked Prompto."

"We need to get that book, then." Ignis and Prompto also seemed to have found a a couple of pots, though once again, none that seemed to match with what they already had. As the four of them made their way back out to the lobby, Ignis mentioned a video clip they saw on the projector screen - one that appeared to document the professor's finding in a secret passage in another country. He had also found a note on the stage podium that was shared between Beth and who they discovered was a boy named Merrick. As he showed it to Nyxia, she felt her stomach turn.

Beth!

Meet me upstairs where we found the pots!

- M.

Below it was different handwriting, which belonged to the girl.

No! Don't go up there! Those things are everywhere. Basement powerplant. I think it's safe.

"Something tells me the power plant wasn't safe," Nyxia murmured in discomfort. Relieved they hadn't made it that far, Nyxia handed the sheet of paper back to Ignis. Once they returned to the library, she showed him what she had discovered, though it felt as if the Ixupi of wax seemed to have left the room by now. Thank goodness.

As Ignis skimmed through the books, Prompto remained out in the lobby, peeking through the other doors they had yet to explore. "This place must be huge," he said. "How many of these things do we need to catch?"

The others were just coming out of the library as he made the inquiry. "It appears there are ten Ixupi. And so far, we have found no match. I suggest we keep the pieces we find in the library until we come across more."

With four, separate pieces sitting on the table, they continued on to one of the doors they had not already passed through, wanting to cover the whole floor before they would go up. The next room they entered consisted of large figurines of various animals - dinosaurs, bird-eating spiders (which evidently gave Prompto the chills), a unicorn, and a griffin.

"That's interesting. It says on this plaque that the griffin is extinct."

"Not in our world, it isn't," Gladio huffed. "These people would probably be amazed if they saw what we did on a regular basis."

"From a sixty-foot giant squid that can pull a small fishing boat into the depths of the sea, to the two-inch poison dart frog that carries enough poison to kill 1,500 people."

Again, Prompto was pushing buttons on random, though the man's voice that protruded was more informative than anything. "Nothing is stranger than the animal kingdom. Is it any wonder that the Ancients worshiped and feared these strange beasts?"

"Sounds like home," Nyxia murmured. "Although I think I might take the two-inch frogs over cactuars any day. They sound cute."

"Not if they shoot poison darts!" Prompto insisted, walking towards one of the other doors.

"There's two different doors," Gladio said. "Think we should split up again?" Nyxia felt him subtly nudge her in the back, and she restrained a snicker.

Prompto approached a set of green doors on the left side of the room, which was closest to the griffin display. "This looks kind of cool," he said, noting the elaborate, vine-like pattern on the door. "It probably sucks inside, though."

As he and Ignis went through the next room, Nyxia and Gladio would follow the other door into a descent of stairs. The first thing she had spotted was a large map that was painted along the floor. It seemed to represent a subterranean world, and Nyxia was keen on learning about the exhibits, even if that wasn't their main objective.

Their gods of worship weren't but so different from the Hexatheon. They had their own god of the seas, which apparently was named Poseidon. Another exhibit talked about one of the seas inhabitants - a siren that would lure men to drown to their deaths. There was even a song that played on the push of a button, haunting, yet beautiful in its own way.

"Maybe a lot of people seemed to think this guy was a total nutcase," Gladio said, looking around on another side of the room, "but only a genius could put all of this shit together."

"No kidding," Nyxia murmured. Behind her, she noticed, was an organ, though it was quite different from any mechanism she had seen before. Instead of keys, closing the clam shells emitted a particular note. As she messed with the notes, she found herself trying to play the siren's song she had heard just moments before. Thankfully, she was musically inclined, having played with cellos for so long...

Suddenly, a giant, stone door in the shape of a face opened up, and it just about scared the hell out of her when it done. Her heart raced for a moment, not having expected that just messing around with the instrument would actually open up another, secret passage.

"This museum is full of surprises, ain't it?" Gladio said, approaching the newly opened passageway.

"Should we go in?" Nyxia asked, though as she took a look at the descending, stony stairs, she felt a little too intimidated to say that would be a good idea.

"Let's wait for the other two," he said, and Nyxia sighed in relief.

Again, she was about scared out of her wits when she heard the voiceover. "You are now entering the unfathomable depths of the sea, where countless ships have sunk, taking with them untold the riches..."

"Prompto!" Nyxia shrieked. "Stop that!"

"Sorry!"

"I'll tell you what... this place totally gives me the chills, and it's not just the Ixupi."

It didn't exactly help that their weapons would do them no good here. They would have to use their wit just to survive.
