Helura's Disappearance

Five hundred years prior to the first Guy Contact novel, Helura, the Medio goddess of earth, mysteriously disappeared, causing a rift between the remaining three gods.

Theories

 * Helura achieved Godi Death and transmutated her form into intelligent life on another planet without telling anyone (which would mean a new godi would have to be born soon)
 * She was somehow killed.
 * She gave up her physical form and became a mortal soul. Jorko believes this is true, especially since Eileen DeVosh looks remarkably like the goddess.

Tzad's Sadness
Tzad blames herself for Helura's disappearance. Before she went away, Helura had been working with Missor to find a way and save the demons they hunted instead of forcing reincarnation on them. Tzad stupidly made the offhand comment, "You'll never be able to save them," which caused Helura to get extremely upset and she was never seen again. After this, Tzad turned her back on Missor and Jorko to wallow in self pity instead of looking for Helura.

Jorko's Fight
Jorko, being an optimist, immediately went to find Helura. He ended up facing off with Zihzu, the demon lord. Unable to exorcise him alone, Jorko locked Zihzu in a stalemate and sent Pyrossus to find the other three godis. He stayed there for 500 years, until Pyrossus returned with Agatha, Jamila and Blaine.

Missor's Mistake
Still loyal to Helura's task of saving demons, Missor began experimenting to find a way and capture demons inside his GodiWatch. Something went wrong and Missor got trapped inside the watch, where he was stuck until Blaine and Jamila find him in the second book.
