Chapter 1: A Request for Help
It was a rejoiceful evening for Camp Half-Blood. Yesterday was the day Luke killed Kronos. Well, not killed, but he disintegrated him into dust and sent him back to Tartarus. However, trouble still lurked around the corner. Only Chiron knew about it. The source of the trouble was England, the land of the wizards. The wizards in England used to be demigods; they were all descendants of Heraptos and Cyrus who were the children of Hecate, but now only wizard blood remains in their bodies. The parents of Salazar Slytherin, Godric Gryffindor, Helga Hufflepuff, and Rowena Ravenclaw were Heraptos and Cyrus. Eventually, Hogwarts was created.
Meanwhile, Chiron was busy sending jugs of root bear to his crazy relatives for helping him in the Titan War. After all, the party ponies did wipe out about half of Kronos' army. Though, Chiron didn't like the party ponies to drink much, he had to award them with something. Apparently the Party Ponies have recently found their liking towards root beer in New York. How did Chiron get all that root beer? Well Dionysus was being nice for once and made a whole crate of Mug Root Bear appear right before Chiron's eyes.
Chiron heard that the Hogwarts war was getting worse, and he was hoping that his good mood wouldn't be ruined by "Hogwarts Business." Luck wasn't on Chiron's side that day when he heard a loud pop come from the Big House's only fireplace. Well it wasn't Dumbledore this time; it was a stronger younger man with a bite mark on his face.
"Great!" Chiron thought sarcastically, "Well, well if it isn't my friend Remus Lupin! So, how is Dumbledore?"
Remus Lupin was clearly sad to mention this subject and with a grimaced face, he replied, "Dead, Snape killed him last spring when there was an intrusion of death eaters. I should have known Snape was a death eater. Then I would have killed him when I had the chance."
With that Chiron grimaced, he replied, "I'm so sorry for you loss, he was a very nice man, but Snape might have different intentions than just killing Dumbledore."
"Well, I'm not here to talk Dumbledore; I'm here to talk about the whole wizarding world. I heard about your win against Kronos, and I congratulate you with your success. I feel bad about this and I hate to ask. Could you spare some of your best warriors?"Remus twiddled with his hair nervously and added, "Hogwarts is on the brink of destruction and I believe Harry might need some help, especially with Snape being headmaster next year. What was once a safe place is no longer."
Chiron thought for a while, and then replied, "Well, camp will be safe without Kronos around, so why not. I'll call upon Percy, Annabeth, Grover, Tyson, Nico, and Thalia to help. Thalia is staying at camp for a vacation and it's about time Percy found out about his family. We'll be there in 1 or 2 hours. Rendezvous at the Burrow, right?
"Yes, and thank you," replied Lupin.
The face disappeared from the fire and Chiron, hoping that this would be the right choice, honked his conch horn and shouted, "Percy, Annabeth, Grover, Tyson, Nico, and Thalia, please report to the big house!"
