Pick a mythical creature – use them as inspiration.

There were 4 left, the last of their kind
Constantly on the lookout for more hunters
Those who wish to steal their light, their power
Thousands of years ago, the fae held dominion
Over this Earth.

But then came gunpowder and nuclear bombs
And railroads and light posts and jet engines
Spewing darkness into the sky, ruining the air
Choking the fae out.

But still they pressed on, fighting for survival
Once the humans discovered them however
Was the beginning of the end of their kind.

It became a sport in certain parts of the world
Trapping and killing faeries, especially the ones who
Couldn't fly or teleport or move between dimensions
Those died out quickly, survival of the fittest.

All that remained of the 6 great fae tribes
Were 4 faeries, passing for human
They alone survived, survived for thousands of years
Waiting, waiting, waiting for an opportunity to rise again.
