30-year-old Leo and Calypso went to Hawaii for the weekend but left there two kids behind with Jason and Piper, they had a 10-year-old son named Alex and a 1-year-old daughter named Bella. Alex had healing powers and stone molding powers(from Hephaestus) but they didn't know about Bella she was too young.

When Jason was shopping with there 12-year-old son Jonas and Piper was cooking she left Alex playing on his laptop she went to check on Bella sleeping she came to a horrifying scene, a Chimera was perched on top of Bella's crib smoke curling from its mouth about to spit fire.

Piper screamed,

Alex came running in"Auntie Piper, what's wrong…" He saw the beast and started moving closer to the crib.

"Alex don't you will get hurt" Piper grabbed him

In a split second Alex ran to the wall and kicked a hatch, it fell down, inside was a board full of daggers and swords, he grabbed a particular thing, a set of throwing knives and ran back to Piper.

"What are you doing with those!" She yelled

That grabbed the Chimera attention, it started creeping towards them, Alex threw a dagger at the beast shoulder, he missed it hit the wall, he threw again and it punctured the beasts eye, it howled and shot fire spinning around, it light the room on fire but all the rooms where fireproof but not the crib, it burst into flames.

Piper ran to grab Bella and stabbed the Chimera with her dagger, it burst into monster dust, Piper started crying Alex was sunburnt red but what about Bella, she looked at Bella blurry eyed.

"Auntie Piper, Bella's ok," Alex said

Piper looked up to see a giggling baby girl, she was fine. She put a tiny bit of charmspeak into her voice and said to Alex

"We don't tell mom and dad or anyone else about this ok, I will"

When Leo and Calypso came back Piper bid them farewell but didn't tell them about it, they found out later when Alex became a knife throwing professional and Bella lit a bully's hair on fire, but Piper never told anyone and she was scared of Chimera's for the rest of her life.
