Timeline

My wiki is set 17 years after Percy defeated Kronos and when the Big 3 were able to have children again. So the oldest a child of the Big 3 is 17 and have to be after the prophecy. But legacies of the Big 3 still exist since many had children over 16 when the prophecy was uttered. Also if they have to be older than 17 the latest they can be born is in 1929 as they have to be 16 or over towards the end of WW2.

Technological Age
The Percy Jackson books are set in the 2010 as Percy is 17 in them and born in 1993. This wiki is set in 2026.

Anyway during 2017-19 Hephaestus/Vulcan, Athena and Hermes/Mercury children made great technological advancements towards both Camps as now they served as secret societies. Demigod children at age 13 have Hestia visit their families and if they don't know about the mythical world and explain it to them as well as teleport their child away where they attend a school designed for Descendants of Divine beings. It has multiple headmaster's which are Chiron, Lupa, Praetor and Dionysus while the school counsellor is Hestia as well as she is the cook.

Classes are taught by Veteran's or sometimes even ghost demigods.

Quests
When a divine being, an Oracle or Child of Apollo receive/give a prophecy for a quest the students it is about venture towards the Quest leaving the school which is the only safe place.

Monster Power Up
Over the years Tartarus angry at Gaea punishment sends monsters out way more frequently and they heal much faster, as well as their abilities are enhanced. They can also smell descendants of Divine Beings.

Descendants of Divine Beings
The school allows descendants of gods, titans and Protogenos in. They all have nametags with their names and below their names will be whatever species they are. If they are a child of gods, titans and Protogenos, they will be called Demi-G, T or P { Whichever one is there parent }. If a Legacy they will be Legacy-G, T or P, if the legacy of 2 or 3 it will go by generation such as Legacy- P, T, G as the Protogenos were the first creations, then titans then gods. Children of Aeolus are allowed despite him not being a god his descendants are treated as Demigods.

This rule was very recent and established in 2019. Monsters descended from divine beings are not accepted into this school.
