Percy's POV:
I can't believe I have a twin sister! She was so cool when she fought Beefhead. I made a mist and threw a drachma in, "Oi Fleecy, do me a solid, show me Sally Jackson at her apartment." Mom appeared, "Hi Percy! Is everything alright? How have you been?" She looked at me in concern, "Mom, why didn't you tell me I had a twin? Seph's really nice and fun!" Mom looked sad, "I knew that raising 2 children of the Big Three would be too dangerous, so I made a decision to give Seph to my best friend. She had shown a lot of talent and I knew that Tartarus would be able to raise her better and train her properly. She always called once a week. I'm sorry for not telling you this." "It's okay, Mom. She's awesome. I love you, bye." I swiped the message. Just as I started getting lost in my thoughts, the door slammed open. "Percy, come to the Big House, Rachel just recited a prophecy."
When we got to the Big House, I saw the counselors sitting on a table with Seph and Nico there helping Rachel to the couch. "So, what's the prophecy?" Katie Gardner, the counselor of the Demeter cabin stood up and read the paper.
"Sea, Death, and Seven will go to the west,
To battle the girl from the metal one's nest.
They will go where a brother and sister unite
And go and avenge with a final fight."
I looked around the room, "Any ideas?" Seph spoke up, "Well, we know that the Seven, along with Nico, he's the death in the prophecy, and I, the sea, will be the questers." We looked grim. It was Seph's first day here, and she was already part of a prophecy. "Well, it could be worse, my first prophecy made me think I would die on my 16th birthday... Now that I think about it, you could have been the prophecy child, how did you avoid it?" Seph smirked, "That's simple, I died the day before, and Uncle Hades revived me the day after," Her gaze softened, "I helped a bit though that day... Since I'm the queen of the monsters, I made them easier to kill. Sadly, I couldn't have stopped them even if I tried."
I held her shoulder, "It's okay, you did what you could, and you protected Olympus when we couldn't. Hades, you got Drama Queen to like you! That's harder than you think! We'll do what we always do. Fight on."
Seph chuckled, "That must be the smartest you've ever said in your life!" The tension around the room lessened as we chuckled. "But you're right, from what I've heard about you guys, you're the best of the best we have to offer. We can do this."
Chiron clapped his hands together, catching our attention. "Well said, so we should make preparations tomorrow and you can leave the day after."
After we left the Big House, Seph walked up to me. "I know you're worrying. What's wrong?" I became confused, "How did you know?" She sighed and waved me off, "It's a twin thing, that's all I'll say, for now, we can discuss it in the morning."
We walked to the Poseidon Cabin and went to bed.
