I can't be bothered to write out the entire search, so I skipped until the part where they find out about it.

The picture is Kiel

Frey's POV

"Are you sure he knows something? Dylas asked.

"Sort of, he's the only person we haven't asked yet, so we have to try. But you should also know that he knows of all the rumors and gossip around here, so if anyone knows something, it might as well be him." I answered back confidently.

"Then why didn't we ask him first?' Dylas asked, probably irritated that he may have wasted a lot of his time.

I simply shrugged and walked inside, luckily, he was just there, reading on his bed.

"Um, Kiel?" I called/asked, catching his attention, causing him to look up, smile at me, and go back to reading his book.

"Yeah?" Kiel answered, not looking up from his book.

"Do you know of any mirage caves? Like caves that are there one day, and could be gone another?" I asked as calmly as I could, in case he thought I was going crazy.

Kiel looked up from his book and left it on his bed while he went to go get.....another book.

"Um, actually I do. I read about it in this book." Kiel flipped through the pages until he landed on a page that said, Fantasy or Fiction? 

"It's said here that there was once a cave called Soul Cave(If this is an actual place IRL or in the game, sorry, I did not know) that only revealed itself during certain times of the month. It reveals itself at the beginning and end of each month. But it's also said to be incredibly dangerous." Kiel explained, skimming through some of the paragraphs.

"Why is that?" Dolce asked

Kiel continued skimming through the paragraphs, sometimes flipping pages when it ends, until he found something.

"It says here that whoever goes into the cave, has to fight powerful monsters, face several mini-bosses(if there unlucky), and make sure they don't stay for very long. It doesn't say why exactly, it doesn't mention anything about why they can't stay for very long, actually. " Kiel explained, with a slight frown on his face.

"Do you know the location of Soul Cave?" I asked

"Yeah, it says it's around Winter Path, at the very end of it. They say during these times there's an extra path way, but it's hidden carefully. But why do you need to know?" Kiel questioned

"It's a request from Venti, we're suppose to find what we can and go there." I explained

Kiel nodded and handed us the book(incase we needed it), while he went back to the book he left on his bed.

I smiled and walked out of the house, with the others following behind me. Now all we need to do is report what we found to Venti and then find and explore this so called Soul Cave!
