72 children

The '72 children' refers to the sons and daughters of Ihy. The Egyptian god's popularity in his youth resulted in begetting a rather large family. In fact one of the first things that we hear Ihy mention to Mrs. Peachbottom is: “I have 72 kids, cut me some slack!”

The identities of Ihy's children are well guarded secrets. At this time, we only know of three currently with a Host on Earth:
 * Izadore:  'Rhythm' follows Izadore's story directly, and has insights into several of Izy's past lives. Izy is currently on Earth being Hosted by Lucas.
 * Pheorex: The identity of Pheorex was disclosed when Izadore had a flashback of being wounded back in ancient Egypt. We know that she is a healer, and at the time of the flashback (321 B.C.) considered herself half Egyptian and half Greek, possibly hinting at her mother's original heritage. Her current Host on Earth is unknown.
 * Rashida: First introduced in the short story 'Still Standing', Rashida is said to be one of the elder god-sons. He has a powerful personality and a long history of warfare. Rashida has a lot of pride in his heritage, insisting that his Host wear an ankh (although hidden under a shirt is apparently fine) . He has a fatherly relationship with his Hosts, including his current partner Bo.
