It Begins

It was centuries ago. Centuries before we moved to this place...
They slaughtered our brethren, our young. We retaliated, coming to a truce to fight, but our dwindling populations were outnumbered by theirs.
Many of us died.
The leaders, like any, wished to protect their clan's survivors. So, they all integrated their powers and used them to create an entirely new world, where Humans couldn't decimate our kin any longer. A portal, too, was made for us to get to the new world.
The world is called the Myth Realm, or the Realm of Myths.
The leaders who had donated their powers couldn't make the journey, for their energy was completely spent. Their kin reluctantly left them behind.

Now we live in this new world, and the time of truce is long over.
