Force Seven: Talisman — M.R. Miller

If it's been a while since you read the first book, this should refresh your memory!

A distant planet, Pinnerite, was destroyed by an evil force that came from space. The surviving Pinnerite race traveled to Earth seeking sanctuary and help to make a final stand against the evil that seemed to be chasing them. They brought with them a prophecy of hope:

From seven lands will come seven,
Strong, united, without fear.
After many years of darkness,
They will bring forth the light of freedom.

The Pinnerite people colonized Antarctica and became known as the Arctics. They are a long lived race whose hair turns pure white when they reach 400 years old. Their light creamy skin and emerald green eyes make them easy to identify among humans.

The evil did indeed follow the Pinnerites to Earth. It arrived in three stages, one for each of the three strange lights in the night sky. The first two stages were showers of light particles that were the essence of evil. They entered large animals first, causing them to morph into vicious human like beasts. Years later the second shower of light resulted in the particles entering humans linking them to the third light. These humans gained seemingly magical powers and a singular mission to take over the world.

The people of Earth knew what was coming, prepared, and fought back. Eventually, however, it was too much and continents became all but totally isolated from one another. Governments and technology were destroyed. Warlords and Dictators took over.

Centuries passed and the third light left the sky. It was a single entity that controlled the evil essences that had invaded Earth in the first two light showers. The entity could take human of or that of a dragon. Her name is Izamore and when she came to Earth, the seven of prophecy were already gathering.
