Shifa

“I wanted to go back to a time before all the sacrifices had been made. Before I had experienced so much pain. But making things right could not mean rewinding the clock. Even Kronos hadn't had that much power over time.
I suspected that wasn't what Jason Grace would want, either.
When he'd told me to remember being human, he'd meant building on pain and tragedy, overcoming it, learning from it. That was something gods never did. We just complained.
To be human is to move forward, to adapt, to believe in your ability to make things better. That is the only way to make the pain and sacrifice mean something.”
― Rick Riordan, The Tower of Nero
