From the beginnings of human kind, there have been creatures of myths and fantasy.
Some are the obvious ones, Fire breathing Dragons... A phoenix rising from the ashes, shedding healing tears.... Pixies, Fairies, Elves... Creatures of the night, such as Yours truely,
Lunarpup, the Moondog.... Owls of wisdom, imps...... Cathulu..... night spirits....
The list is tooooooo long to name every one.... It seems humankind's mind created a creature of some sort to explain what ever was unknown and mysterious.
Sometimes, to scare the kids into bed..... " Get to bed now Johnny, or the boogy man will get ya!!" Some, and maybe most, are based in fact.
The Realm of fantasy is full of everything we have in the real world, but in extremes.
You don't walk to the store, You mount your trusty house dragon and fly to the hunt, with your magic bow of true aim.... And if lucky, will find an everlast beast for the feast. The Everlast Beast got it's name, because for such a small creature..... as you cook it...it's meat becomes next to endless....two can feed a village of 400 for the winter, and is only the size of an elk.
Seeeeeee,???? lol the necessity to explain ..... can be a mother of myth.
Everlast Beast....Yea Right...give me a break.... LOL
Think about it thou.... It does still continue. Urban Myths, Big Foot, LocNess<Nessie>
As long as our minds are FREE, we will always have fantasy to help us through.
