"A daimon? Impossible. Percy is a demigod." Annabeth shook her head in disbelief. Chiron gave her a sad look.
"Not a daimon, Annabeth. A demon." The old centaur corrected her gently. "And not the kind your Kane friends battle." He added, almost as an afterthought. Dean opened his mouth to question that statement, but San elbowed him and shook his head. Later then. Dean thought to himself as Sam explained demons to Annabeth.
"Demons are just malevolent spirits. They are created from human souls that have been corrupted by their time in Hell. Most are extremely evil, and also very powerful. But Percy was an archangel in a Vessel." For once, Annabeth had a confused look on her face as she looked between them.
"A vessel is a human that an angel inhabits in order to manifest on Earth. Vessels are the safest and most conventional way for angels to interact with humans on Earth, as our true voices and visages can kill, and in the very least severely harm humans." Cas looked around the Big House and then at Annabeth as he explained.
"I do not know how long Percy has known he was an angel, but he knows now. His powers have grown immensely. Due to being stripped of his grace, and being in Tartarus, he has grown dark. He found me, and he explained to me what he was going to do. But something felt off about my brother." Cas said, and started looking like he was off in his own little world, a worried look on his face. Dean glanced over at him before turning back to the pair in front of them.
"Cas said that Percy was working with Lilith." Chiron's face changed from calm, to a matter of panic in seconds.
"The seals." He said. The brother's head snapped up.
"What does Percy working with Lilith have to do with the seals?" Sam asked, looking at the centaur.
"Perseus unintentionally broke the first one. But if he is now working with Lilith, one of the more powerful demons, he must be helping her break the rest needed to free Lucifer." Chiron answered. He cast his eyes towards the floor as Annabeth glared at the space between herself and the hunters.
"What is a seal?" She asked finally, looking like she was about to pull her knife on someone. Sam and Dean glanced at Chiron, seeming as he knew the girl best, and also because the blonde scared them.
"The 66 Seals serve as locks on Lucifer's Cage that God prescribed or inseminated as events. Even though only 66 need to be broken, there are over 600 possible seals." Chiron told her. The daughter of Athena's brow furrowed.
"That would make it even harder to stop her. You aren't able to predict which one she is going to break next, and it's not like she'll help you with that." Annabeth gave a dry laugh.
"This is like every war we've ever fought." She sighed. "Chiron, we might need to get everyone ready for another war."
"I know, my dear. I know." Chiron rubbed a hand across his face. Castiel chose this moment to speak up.
"My brother said he would help us as well, but he will also have to tell Lilith some of our plans." The angel said. Annabeth smiled softly, remembering all the times Percy had risked his life for her.
"You must remember, this is not the Perseus you knew. For the first 17 years of his human life, he truly believed he was a demigod. But then he remembered his life before his fall." Cas cautioned the young demigod. Her simple aspect of happiness fell from her face and a look of heartache rolled onto her face. Chiron reached out his hand to comfort his and she leaned into it. She closed her eyes to keep tears from falling, but a few escaped. Sam's heart went out to this girl. She had lost her boyfriend, but knew he was still alive. Sam had a hard enough time after Jess died, but knowing your girlfriend or boyfriend was out there, but you just couldn't find them, must have been so much worse. After few seconds, she stood up straight and wiped her eyes furiously.
"Chiron, we need to tell Frank, Hazel, Nico, Jason, Piper, Thalia, and Reyna. They deserve to know." The curly hair demigod implored, her eyes begging him. Chiron relented and nodded. Annabeth jumped up and ran to get a drachma, crystal, and water. Just as she reached the door, they all slammed shut. She jumped back and pulled her dagger, the blade glowing with a bronze light. Cas slipped his angel blade into his hand as Sam and Dean both pulled guns hidden in their waistbands. The brothers slowly spun in a circle as the others looked around. Annabeth tried the door but it wouldn't open. A laugh rang through the room and Annabeth's eyes widened, recognising the voice. A figure appeared, leaning against the Pac-Man game. His sea-green eyes sparkled darkly as he spoke, looking at each and every person in the eyes.
"Home, sweet home."
