Annabeth POV:

A few days ago, Percy and I were notified of something at the ministry, soon taking some time away from Hogwarts. "Dumbledore said there were a few cases of strange witches and wizards in the wizarding world, but they blended in so easily that it isn't certain," I said as we walked around the streets of London. "Last we spoke with Chiron; he mentioned that there have been times where they couldn't reach demigods even if there were evidence of their existence; being in the magical world only concealed them further."

"It is sort of an extension from Hecate's realm," Percy said. "Kinda like the magicians we met a while back. Magic, but not the magic of which we're familiar. Still, if we can know more about the past relations, it might help with our current situation."

"It's not just that," I quickened the pace, my voice lowering into nothing more than a whisper. Percy leaned closer to listen. "Chiron mentioned there was a demigod several decades ago. He didn't stay too long in CHB or Camp Jupiter. In contrast, he spent an awful lot of time in London, England. He was an oracle. There were others besides him, but he was one that Chiron remembers well."

"Yeah, but Chiron never got his name," Percy replied. "Let's hope the ministry has more information on what we need." That was for certain. Though, where we were heading, I would have been shocked if we found nothing useful. While the ministry undoubtedly has gathered a lot of records on different magical occurrences and situations, the place we headed to could be considered a pinnacle of research. An archive of exploration, analysis and knowledge gathered throughout the years: The Department of Mysteries.

Magic is useful for many reasons, but I still preferred to use more familiar items like an invisibility cap and a dagger which were easier to rely on for me. As expected getting in wasn't a walk in the park, but it went rather smoothly. We were more concerned about finishing our investigation and getting out without much trouble. The Department of Mysteries was located in some of the lowest levels of the Ministry of Magic. Surrounded by black-tiled walls without any windows or doors, it reminded me of a fancy prison. The only light was provided by torches, letting blue-white flames make the surroundings slightly more visible. Percy looked back to the door we came from, likely one of the only exits. If we couldn't escape from there, there were always more chaotic options.

At that moment, we stood in a circular room with a dark marble floor that seemed almost placid. There were twelve handleless doors, all looking the same. Once one closed, the walls rotated, making navigating even more difficult than it already was. In some ways, it reminded me of the Labyrinth Percy and I went through before we fought Kronos. Naturally, the circumstances at that time weren't very similar to the one we were in at the moment and the overall feeling when searching our way through was also different, but it still brought back some old memories.

After coming in, Percy and I spent a while going through the doors, trying to find a room that had what we needed. Some we passed through quite easily, others were taken note of for later. "Brain Room," Percy remarked after we passed from the Space Room to a room of clocks. "I think that one should be the first one we visit after we look for some prophecies."

"All right, but I'm not sure how we can look into them." If we got too close to any of the jars, tendrils would immediatley lash out.

"We'll figure something out," Percy replied, finger inching near a clock on the wall. In contrast to how the Department of Mysteries looked when we first entered, this division was full of sparkling lights. Nevertheless, what was more attention-grabbing were the clocks that covered the Time Room. All kinds of time-related devices filled the chamber, mainly clocks of every description. At the end of the room, there was a large crystal bell jar where much of the light was concentrated. Behind me, Percy soon withdrew his hand from the clock, ultimately choosing not to touch it before catching up to my side. "Don't tell me you aren't curious about what it's like?"

"Percy, my mom popped out from a brain. I popped out from a brain. Remember?" I said, passing by a large rack. I wonder what this was for? Most of the shelves had nothing on them, others just had a few necklaces. I stopped to peer over at one of them. At the centre of each one, there was a small hourglass-like figure. Ah. Time-turners.

"That doesn't answer my question." Percy teased, stopping at my side. "Cool time-turners, I wonder why they don't just put them somewhere else instead of leaving them here. It would save space."

"There should still be researchers coming in here now and then. They probably took the rest away. Maybe these will go with them as well later on."

"Let's just hope they don't come back to do so right now." We chose a date and time where there wouldn't be as many people and if things needed more time then we already got multiple days off from school and a very useful ability in hiding from people.

I smiled at him before we headed into the next division. This one was filled with shelves that reached the ceiling, each one full of nothing, but dusty, glass orbs, something that could be completely gripped in my palm. The room was incredibly cold, giving off chills as soon as I set foot into it. Around the walls, there were blue flames as lanterns just like in the other room, but I doubt that added any heat. "The Hall of Prophecy," I remarked. "It's like a record of every prophecy conducted in the British wizarding world."

"Maybe beyond too," Percy noted. "How do we find out if any oracles did any?"

"Well...we can—Percy! Don't touch them now!"

"Don't worry," He assured me, moving his hand away from the glowing orbs. "Fighting monsters and going through random quests for the past years haven't done anything." Unfortunately for us, we weren't running on much information. We had some names of oracles that came to Britain but were unsure if they ever made contact with the ministry. For the time being, it was best to go through all the unknown ones first. "He mentioned a prophecy he made there," Chiron had said. "Something concerning two worlds, but he didn't say much else." What we did have was whatever Multivitamins we had from Hermes. There weren't many remaining, but I doubt they would expire, and we didn't have many other options. Cabin 20 was tinkering, but they said it's best if we used the vitamins. This time though, it was easier to guess which ones would do what we needed, though I wasn't sure how long the effect would last, just like how I wasn't sure how long we had been looking at prophecies.

"Someone's going to have a bad day," Percy remarked, putting another orb back. Despite the overall success of this trip being rather low, it was still intriguing looking at all these predictions. I put another prophecy back onto the shelf. "We should look at the other rooms, there's nothing here and we didn't take a large portion of the vitamins. I don't think we can continue."

"Good idea." Percy got up from where he was crouching. "But I think this one might be a winner."

"Cassandra Trelawney," I looked at the name. "This was made quite a while ago." It wasn't the first prophecy we saw by her, but I suppose another one wouldn't make much of a difference. Unlike the other prophecies, instead of a voice replaying it seemed to resemble a memory. We both emerged into a scene where a young woman was sitting at the of a table. She had frizzy brown hair and was wearing some everyday clothing, but gave off a feeling of elegance. She was soon joined by a man with a hunched back and poor clothing. Looking as though he hadn't had a bath for a while, he took a seat on the opposite of who I assume was Cassandra Trelawney. "How's your castle?" She gave him a pointed look.

"Fine. How are you?"

"Rather be doing other things, but what can I say? Some goals should have priority."

The man sneered, his fingers fiddling with his wand. "Cassandra Trelawney. Such a famed seer, but so rude."

"Raczidian, the dark wizard living two centuries in the past. I'm surprised you got the guts to come out. I'm guessing once this talk is done you'll return to being holed up in your castle. Your reputation isn't very pleasing to the ear, is it?"

"Let's skip the pleasantries, shall we? Herpo the Foul. A menace for regular wizard folk, a legend for dark wizards, but every witch and wizard in the wizarding world has likely heard of him. He created the first known Basilisk, the first Horcrux: a true genius. What people don't know is how much of a connection he had to another world. Many people thought he was already crazy, his ramblings of another world were something not paid attention to." Raczidian pulled out an ancient-looking record, several sheets of paper falling out. "He made notes himself amongst his other research about his heritage, his family...another force that can strengthen—"

"—or harm."

"—the wizarding world." Raczidian pressed his lips together into a thin line before smirking. "That'll have to be for us to see. You have some connections as well, don't you? Family history tracing to the unknown."

"Heritage can be a blurry thing sometimes." Cassandra Trelawney placed a hand at her temples, rolling her slim fingers in a slow rotating motion. "I had a vision recently, one of a day when the line between these two worlds start to fade onto each other until there isn't one anymore. I don't normally prefer to interfere in future events, but a sinking feeling in my gut tells me I have to know more first: lay down a foundation."

Greeted with an expression that seemed to be both serene and tense, Raczidian only stood up with a smile, stretching out his hand. "All right then, let's lay down this foundation." Once the two hands shook, the recording ended, letting our surroundings melt back into the cold room of prophecies. Hesitantly, Percy's hand reached out but didn't dare touch the orb. After a quick thought, he stood up. "Annabeth, I'm not sure if the vitamins are still working. Maybe we should leave this one here for them to find. They might think of it as an accident. We should get moving."

"You're right," I said. Still, I couldn't help thinking back to the vision we saw. Rather than a prophecy, it was a recorded exchange instead. Then what was doing there? And how was it even documented in the first place?

Besides that, there was also the oracle Chiron mentioned. If the ministry didn't have it, maybe there was no record. Still...

I couldn't help but get a feeling of apprehension.

Hello, how's everyone doing? :)
