As you may or may not know, Galator raised Raven so he's like a step father. He is also the second oldest dragon making him the biggest after satan.

Galator will do anything to protect Raven and those she loves. Dragons live forever unless killed. Beings like Raven do not "live" forever.

A pact was made one ay between Raven's demon, Econavious, and Galator. To protect Raven and Ariayous from being dragged to hell and sealed Galator would spend a long "sleep" in the earth to save them. But to keep his mind awake during this time 100 years to 1000 will be taken off Raven and Ariayous's remaining lifespan in fate, let it be 60'000 years or just a month left to live, no matter what they would not stay in hell forever.

When they do die they must spend however many years in hell that was taken from their lifespan, and knowing Econavious shes going to rule hell in this time, after this time is done tey will return to so called life.
