"Chiron, what does he mean Athena's missing?"

"He means that she's missing. That makes it obvious why her children have all 'fallen asleep'."

"What? How is it obvious?" Percy yelled.

"Children of Athena have a stronger connection with there mother then any other demigod with there parent, because of how they were born."

"Hold on... Because of how they were born? Aren't  they born like the rest of us?" Magnus asks. 

"No. Athena is one of the three maiden goddess from Greek mythology. There's Athena, Artemis, and Hestia."

"Um... Don't take this the wrong way, but if she's a maiden goddess, how does she have children?" Alex asked.

"Children of Athena are born similar to the way there mother was."

"What? How was she born? I mean I know I was born weird, but I was born the same as the rest of you." I've never really gotten to know Alex, but I think I know how she/he was born. But instead of asking, I answer the question.

"Athena was born from Zeus. She doesn't have a mom, because she was born from his head. Her children are born from her head, except for Athena was born fully mature and in battle armor, and her children are born as infant's, there pretty much born the same way."

"But doesn't that mean they don't have a dad?" Alex asked.

"Um... That's hard to answer. They have a dad, but... Um... They're inspired from there dad, which means there dad is kinda like an adopted dad." 

"Okay... That's weird. Kinda cool, but weird." she/he said.

"Okay, now how do we wake her... them up?" Percy asked. 

I couldn't bring myself to answer, but Chiron was, "I don't know. This has never happened before. Except for with Pan, but he didn't have any children."
