Percy POV

It was around 9 AM when I arrived in York to meet with Magnus. It had taken Annabeth sending an Iris Message the night before to remind me that I had to meet up with them, so I made sure that I got up earlier to get there.

Unfortunately, I got up there too early, and had to wait around for hours for them to show up, so I had a couple cups of coffee to give me some energy.

Now, there are a few things everyone should know in the mythological world 1. Never say that something bad hasn't happened yet (The Fates are always listening and will get their revenge in the next 5 seconds, and yes you can count it) 2. You should never tickle a sleeping dragon (Dragons can't laugh so they sneeze instead, and when dragons sneeze, their snot gets everywhere. Not only that but it's a pain in the arse to get snot out of clothes) and 3. The most dangerous of them all: Never give Greco-Roman demigods coffee.

Yes, it may sound ridiculous, but it is true. Even the non-ADHD demigods get affected by it and every demigod has a specific quirk that they get when they have it. When Frank had some on the Argo II, he spent about an hour changing into different creatures, half of whom I had no idea existed, and when Leo had some, he quite literally started bouncing off the walls. Even Annabeth was affected! She somehow managed to read two different books at once, by reading one book with one eye, and the other book with her other eye (Will was completely baffled by this saying that it should be impossible, before Annabeth replied saying that controlling water should be impossible, as she pointed at me. Will conceded the point).

It is due to this; all Greek demigods are given coffee in Camp Half-Blood so that they can learn how to control their coffee addled state so that they don't have to learn about out in the mortal world. Nobody wants a person to suddenly start glowing for some reason when they have some coffee in a café (Will was unfortunately stuck with that trait)

Now, for my quirk, you will have to see.

It was around 11 AM when a Viking longship showed up in the harbour, in the colour of I can't believe it's not butter yellow. If that wasn't the big enough clue that the ship came from myth (only gods can be this detached from the world to give someone a ship of that horrible colour) then the ship was sailing itself, the oars moving by magic.

I made my way over to the ship and climbed aboard. I know that it may be rude, but nobody was on the deck, so I made the executive decision to meet them on their ship.

"Hello!" I called out, "I'm looking for Magnus Chase!"

That seemed to work, as 6 people came out from underneath the deck, all wielding a multitude of weapons, ranging from battle-axes to a garrotte wire, including Magnus and Alex (Annabeth told me what Magnus looked like, and Magnus tended to over describe Alex in his letters to Annabeth).

A girl with a hijab, stepped forward and replied "There is no Magnus Chase aboard. The closest name we have is Mango Cheese,"

I blinked for a second before saying, "Well that's a name worthy of Dionysus,"

"Dionysus?" Alex asked

"Greek God of Wine," Magnus answered, "So you must be Percy,"

"Got it in one," I congratulated, "And you must be Magnus. It really is weird how much your alike, considering Annabeth gets her grey eyes and blonde hair from her mother, which is rather odd as Athena has black hair,"

"You know this guy?" a boy with a bayonet asked

"Not exactly," Magnus replied, "TJ, Mallory, Sam, Halfborn and Alex meet Percy Jackson. Percy, meet TJ, Mallory, Sam, Halfborn and Alex. Percy is the fiancé of my cousin Annabeth" Magnus pointed to each of his friends in turn when saying who they are.

"Hi," I said, "Er, quick summary, I'm Perseus Jackson, son of Poseidon, Greek God of the Sea and other things, and I am here to teach you how to use the sea to your advantage,"

Everybody (except for Magnus) stared at me in shock, before Halfborn said "Great, Greek demigods exist. What's next, an Egyptian demigod? I don't think this world can get any weirder"

"The Egyptian gods don't have demigod children, instead they possess the people that study their form of magic, but you generally have to be a descendent of one of the Pharaohs," I said

"I stand corrected," Halfborn replied, "Things do get weirder,"

"Of course, you got it wrong you stupid old oaf," Mallory yelled at him, and pretty quickly it descended into a ginormous squabble match

"Ignoring them for a minute," Sam said and stepped forward, "I understand that Poseidon is the God of the Seas, but how does this help in our quest, as I don't believe that you will be continuing with us,"

"No, I won't be joining you," I replied, shaking my head, "I am actually in lull in a quest that I am doing right now so I offered to help. Anyway, I'd say that I'm qualified to help by the fact that I have had to sail in two different quests that I have been on, including one last summer."

"Pretty useful experience then," Sam nodded

"I do have to ask, why did it seem as though three of you were getting ready to leave the ship when I climbed aboard? TJ, Magnus and Alex that is." I asked

"That's because they were," Sam told me, "They need to challenge the giant Hrungir to a fight so that he can tell us the location of the Kvasir mead,"

"Okay, I can make do with half the crew missing," I mutter under my breath, "It's a good thing then that what I will be teaching you is less about sailing, more of how to control yourself on a boat,"

"Why does how we control ourselves on a boat matter," Sam asked

"So that you aren't surprised like this," I said, as I walked over to Halfborn and Mallory, and smashed their faces into one another

The two of them glared at me. "What was that for!" They yelled, and promptly began to glare at each other

"Arguing," I said glaring at them, "You're supposed to be a team that can trust one another. So, what the Hades are you arguing about?"

"Well, she's just being an absolute bitch!" Halfborn yelled

"And he's being an absolute knobhead!" Mallory cried back.

I stared at the two of them. "Lovers quarrel then," I decided.

"I absolutely do not love him," Mallory vowed, venomously, "I hate him!"

"And I hate you too," Halfborn spat back

"One thing with being close friends with a daughter of Aphrodite, is that you pick up on things to do with love. One of those things is that love and hate are on the same spectrum, and it is very easy to warp love into hate and hate into love," I told the two of them.

Both of the einherjar gaped at me in shock. "Now that the two idiots are quiet, I suggest that you get on with your quest now," I told Magnus, Alex and TJ.

"Ooh, goody! I'm going to thank so many British people," TJ cheered, and hopped overboard onto the dock, with Magnus and Alex soon following

"Now then," I said as I turned back to face the Vikings, "Let's continue,"

Honestly, I expected it to take longer to train Norse Einherjar how to work together as a crew on a longship. Then again, I had talked to them halfway through their journey, so I should have realised that they would figure some things out through trial and error.

I had to explain to them how to properly jump of ships if they need to be abandoned, though I was unable to let them try it as it could kill them, as well as how to the tie some more advanced knots.

I also managed to get through to Mallory and Halfborn enough that they are no longer screaming at each other whenever they can. They now actually just speak to each other amicably when necessary, refusing to talk to each other when not. Another thing learnt from Piper, indifference is the opposite of love, not hate. Hate and love are on the same spectrum, but love and indifference are polar opposites.

Unfortunately, while docked in York, some local water creatures attacked, apparently called Vatnavaettir, causing my coffee quirk to activate, leading to me gushing at how cute they are.

Yep, my coffee quirk is whenever I meet a sea creature, I immediately turn into an Aphrodite child in front of them, squealing about how cute they are, no matter what they look like. My biggest dread is that I will become high of coffee and then meet Cetus.

So yes, I refused to let anyone kill the Vatnavaettir, one because they were adorable, and two, because the only reason why they were attacking the crew was because they wanted some friends to play with underwater. It wasn't their fault that the people that they chose could breathe underwater. How inconsiderate of them.

Even Sam agreed with me. She became fast friends with one of them called Joey, and thankfully she could shapeshift into a fish, allowing them to talk to one another, without me being there to translate.

Eventually it turned to dusk, and I had the option of letting the Order know that I was staying here the night or going back to Grimmauld Place. I chose to stay with the Norse because Sirius' house certainly lived up to it's name of being grim and old.

The next day continued very much the same as the day before, teaching the 3 Norse einherjar, though we do go into the town to have some breakfast, much as we had the night before for dinner.

It was around 12 o'clock when Magnus, Alex and TJ returned back to the ship, looking a little worse for wear, but alright.

"Did you get what you wanted?" Sam asked

"Yep," Magnus said, proudly, "The location of the Kvasir mead is up in Norway,"

"What does that even do?" I asked

"It will help Maggie when he challenged Loki to a flyting," Alex replied

"And what the Hera is flyting?" I asked again

"Insulting each other through poetry, and Beantown isn't the slightest bit poetic, so he needs the mead," Mallory explained

"So you need it do poetry?" I asked Magnus, who nodded, "Then why didn't you say? I have the easiest solution to that,"

"What? How?" Magnus asked

"I could call up an Apollo kid to curse you to speak in poetry until it runs out. And they set the time limit and type of poetry," I explained

"So, you could ask someone to make someone you don't like to speak in rhyme for eternity, in theory?" Mallory asked, eyeing Halfborn suspiciously. Oh well. Their relationship is better. They can figure out the last leg of the stretch on their own.

"We are doing this plan, immediately" Alex yelled out "So much blackmail,"

"No, we are not doing that," Magnus vehemently denied, "Speaking as a poet for a while will be enough. Besides, how do you know if it will work?"

"It likely will as I can feel that this ship can be stored as a handkerchief through my powers," I replied, dismissing Magnus' worries, "You don't know how hard it is to stop myself from turning the ship back into a handkerchief and dumping everyone in the water."

"How is that difficult?" TJ asked

"Do you know how amazing of a prank that would be?" I said, "Standing on a deck of a ship, that just suddenly disappears, and you fall into the water. Hilarious!"

"I agree," Alex nodded, seriously, "As long as I'm not the one being dunked,"

"See!" I cried out gesturing to Alex, "She?" Alex nodded, "She gets it, mostly. She just needs to understand it would be funny if she fell in as well," Alex scowled. "Should I continue with the lesson, or do I need to go now for you to continue your quest?"

"I think that you should be fine," Magnus said, "We just need to leave tonight,"

"Perfect," I grinned, "Now it is time to teach you three idiots what I taught those three idiots,"

Teaching TJ, Alex and Magnus was much easier when two of the members weren't trying to tear each other's throats out. It also got easier when I found out that TJ has to accept any challenge thrown at him, so I just challenged him to learn all the knots and he was raring to go.

Quite quickly, it was becoming dark, and the crew of the Yellow Banana had to leave to go to Norway, and I had to return to Grimmauld Place.

"So, I need to be off to London now, and I hope that the information has been of good use," I asked of them

"It's been brilliant," Magnus said.

I was just about to reply, before a familiar voice called out behind me, "Percy!"

I jumped and spun around, to see my beautiful Wise Girl in the screen of an IM. "Oh Annabeth, I was just finishing up here. What is it?"

"First where are you, and second, Voldemort has taken the bait," Annabeth told me.

"Perfect, I'll be off to tell the order in just a second and I was helping you cousin as that was today," I explained to her, as Annabeth slapped her forehead in a face palm, probably thinking to herself about how she could have forgotten about me meeting Magnus.

"Okay, now remember, it's in the Department of Mysteries, so make sure that's where you appear," Annabeth explained to me, while I nodded. Department of Mysteries. Got it. "Love you," She called out

"Love you more,"

"Not possible," She answered before I could reply.

"Well, that was adorable," Alex said

"Shut up," I said, blushing up a storm, "Whose, the guy, gal or non-binary pal in your life then?"

Alex immediately began stuttering out a denial to the claim, but not before taking a side glance at Magnus, that was missed completely by him.

I said my goodbyes to the Norse, and vapour travelled back to 12 Grimmauld Place.

"Percy," Sirius called out from where he was sitting at the table, reading a newspaper, "What is it?" He asked when he noticed my face

"Voldemort has taken the bait and has lured Harry to the Department of Mysteries. Both Annabeth and Zoe are on their way," I reported, as Sirius' eyes widened, and dropped the newspaper.

"Shit," Sirius cursed, before he ran over to the other side of the kitchen and pressed a button. Why there was a button there, I have no idea considering this it is about the only bit of technology I have seen in this world, but I guess I will have to roll with it.

Immediately, several members of the order apparated into the room, including Tonks, Shacklebolt and Moody.

"What is this meeting for?" Moody asked

"Voldemort has taken the bait, Harry, Annabeth, Zoe and some of his friends are on their way to the Department of Mysteries," I informed

All order members present widened their eyes, before Moody quickly recovered and began barking out orders. "I want everyone to make sure that their wands are in top condition, before we apparate. How are they getting down to London?"

"My guess is by Thestral," I answered, "They don't have enough brooms and Zoe, Annabeth and Harry all know of their existence. My prediction is that it will take them little over an hour for them to get down to the ministry,"

"We shall appear to them inside the building," Moody informed us, "Suit up,"
