1)Don´t know.Ask other members.

2)It´s the name I gave to the evil character behind FF8 (X).
It is based on the Legend of the great Hyne(see on the game).

The interpretation I give to the legend goes like this:

Ellone had sent Vascaroons counsciousness to many different times.
One day she accidentaly sent him further on the future into the body of a person.
This person was talking to another person and called his name.
Ancient Centra persons speak with a different accent than present people.
So Vascaroon spelled the name of the person he saw on the future as "Hyne".
They (Vascaroon and the "White Seed") realized that it was the person who possesses Ultimecia.Vascaroon watched over Ulti´s castle and used to paint what he sees on the different eras(on a symbolical way).
After that,Ulti was not possessed anymore(she was but pretends not).
At this time the Zebalga tribe wanted to work with Ulti to take over the world.
But they found that Ulti becamed good and get angry.
Vascaroon told them everything and they seek for "Hyne" over the entire world.
However Ellone´s powers weren´t clearly understood yet so they don´t knew they were seeing other times and Hyne lives on the future.
They never found Hyne.
But the citizens of the future were also enabled to see the past which made Hyne angry.
He then created WOTC.
