((This Time Line is set to the HP Movie: The Order Of the Phoenix. The Wizarding World doesn't know any of the Gods exist and they only think they are Royals that have control over stuff. It's based on 'American Royalty at Hogwarts' on ao3 and wattpad.))

((The other rulers are Royal Duchess Olivia (Athena), Royal Duke Sol (Apollo), Royal Duchess Diana (Artemis), Royal Duchess Astrid (Aphrodite), Royal Duchess Terra (Demeter), Royal Duchess Juno is also known as Queen Juno (Hera), Royal Duke Duncan (Ares), Royal Duchess Adara (Hestia), Royal Duke Ignatius (Hephateus), Royal Duke Nos (Hypnos), Royal Duchess Iris (Iris), Royal Duchess Belle (Minerva), and Royal Duke Noah (Hemes). The main rulers are King Hadrien (Hades), King Zane (Zeus), and King Gale (Poseidon).))

In the Wizarding World, you and the other Half-Bloods are Royalty, Cause Lady Hecate Created the Wizarding World many centuries ago. And made the Gods and Half-bloods royals by creating the Olympian Kingdom, and now you have to go to Hogwarts with some of your friends/siblings have to Represent "The Olympian Kingdom". But first you guys have to meet with the Order of the Phoenix since they requested to.

So that's how you guys are now at 12 Grimmauld Place, meeting with the Order of the Phoenix and some others. It had been a long time since some of the Olympian Kingdom children have been seen and met for a long time. The Olympian Children representatives are different than expected, but from the information they have heard it does match them. Most had scars and definitely have been in war. 12 Grimmauld Place belongs to Sirius, who uses it for the Order of the Phoenix.
