Though peace had returned, remnants of the past still stirred.
In the Forbidden Forest, the magical barrier had been reforged, but centaurs reported strange flickers of light deep within—ghosts of battles past, or perhaps echoes of magic too old to understand. Firenze stood at the forest's edge, watching the horizon. "Balance returns slowly," he murmured. "But it does return."
Back in Hogwarts, Hermione, Annabeth, and Reyna had gathered in the library, pouring over old texts left behind by the Founders.
"There's more here," Annabeth said, pointing to a journal Rowena Ravenclaw had enchanted. "She predicted something like Aeon's return centuries ago. She called it The Shadow Cycle."
Reyna frowned. "So the gods knew… and didn't say anything?"
"No," Hermione said, running her finger along the glowing runes. "They didn't know. But she suspected. It's like she was trying to warn future generations in her own way."
"Guess we found it just in time," Reyna muttered.
Elsewhere, Nico was speaking with Hades. The god of the Underworld stood in a quiet glade, his expression unreadable.
"You knew about Aeon," Nico said quietly.
Hades sighed. "I knew of what he was, but not who. By the time I suspected, it was too late. I wanted to protect you from what I couldn't stop."
"I don't need protection anymore," Nico replied. "But… thanks for trying."
There was no warmth in Hades' eyes, but for once, there was something close to pride.
Meanwhile, Thalia climbed the Astronomy Tower alone. She lit a spark with her fingertips and watched it dance against the wind. "I don't trust peace," she muttered to herself. "But I'll fight to keep it."
Down in the courtyard, Harry, Percy, and Jason watched younger students—both magical and demigod—training together. No lines divided them now.
"Think it'll last?" Jason asked.
Percy shrugged. "Depends on us, doesn't it?"
Harry nodded. "Then we better make it last."
And beneath the castle, unknown to all, a faint pulse of energy stirred in the chamber where Aeon had fallen. Not malevolent, not dangerous… just memory. A final echo.
The past had been dealt with.
But its lessons would never be forgotten.
