The Pact of the Big Three was an oath made by the Big Three gods Zeus, Poseidon, and Hades, to no longer have demigod children and to no longer involve themselves in their affairs. This pact however was broken when the gods had Thalia, Percy, and Nico. You know the story of these warriors however this one is the story of the grim reaper. A nickname given to a demigod who slayed monsters by herself. This demigod is not the daughter of Hades but the daughter of Poseidon. Her name is Hallie Jackson, twin sister of Percy Jackson...

She also quickly grew to know to always follow her gut feeling, a feeling that saved her life multiple times. After being kicked out of the orphanage at the age of seven she struggled to survive on her own but she soon understood why it was that way. Her upbringing was filled with monster battles and training on her own, without knowing what was awaiting her up in Long Island.

However, that all changed when she was doing a quest for the god Apollo and ran into some unexpected people...
