Hidden beyond the next tree. Over secret paths only a few can see. Through the arches of branches and flowers. There is a world of magic and wonder. Teal skies. Vivid greenery. Unique flowers. Maroon earth. Only on the continent of Argentum, in Astranar, can people cross over and discover the enchantments and peoples of the Mirror World.
A simple name, perhaps, while others over the world may have slipped through cracks, they called it different things. Underhill. Wonderland. The Never Ending Wood. Ever After. In Astranar, the natives know that names have power and the true name of the World is best left to those that live in it. They simply call it the Mirror World for it mirrors their own.
When Astranar is in the heart of summer, the Mirror World is in the deepest folds of winter. And while in Astranar, it takes a powerful spell caster to work anything beyond basic spells, in the Mirror World, magic is as easy as breathing—for better or worse!
If one could see both the Mirror World and the mundane world at the same time, one would be able to see the towns co-existing in the same places! The people going on about their lives doing everyday things. For the people of the Mirror World have the same wants and needs as the people in the mundane world no matter how different their appearance.
And oh how different they are! Those that live close to humans can be breathe taking and magical. Fairies in their tiny snow globe sized bubbles. Elementals that take on the shape of humans or giant birds. Griffons that share a passing resemblance to eagles. Deer with colorful coats and exotic antlers like flowering branches and crystal. And many different types of sheep.
Then there are the magical beings that only choose to share the shape of humans. Though their skin is anything but human looking as if someone took liquid metals, and glowing paints to create abstract and fantastical designs. Some may have wings to mock the humans and their tales of fairies (or is it mockery?). Take care of those that live in the ponds.
Those that live deep in the Mirror World have names and faces familiar to the mundane; Santa Claus, Cupid, The Pumpkin King/Jack Frost, Mother Goose, and the Green Man. They come closer to the mundane world around the solstices and holidays when the veil between worlds is thinner. The ways to their towns and castles are only available for a short time each year as they are celebrated (or appeased.) Perhaps, if the main character helps them enough, they will open special places, special towns for the player to visit them all year round.
Then there are the horses! Horses in the Mirror World are the horses of every rider’s fantasy. The most prolific and easiest to find, because often they find their own riders, are the magical color changing horses. Reminding outsiders of a Fjord horse, in the mundane world they come in all shades of dun and have bi-colored manes. In the Mirror World, their coats and manes become an array of bright, muted, or pastel colors. And in the Mirror World, they can talk to their riders. (This may or may not be welcome depending on their personality.)
One can make friend with unicorns, tame the wild pegasus, help the rainbow alicorns, and even discover beautiful nymph horses that take after plants and trees. They can take their rider to places no normal horse can reach (much to the MC’s main horse’s displeasure.)
A word of warning, as with the magic of Astranar, in the Mirror World there are places of Light and places of Shadow. Woe betide those who are of opposite sides stumbling into places they shouldn’t be. Those of the light, beware the arches of dead branches covered in moss. And those of the shadow, beware the arches of living branches covered in ivy. If caught inside, riders of the rong faction have to flee to avoid capture or bargain for their freedom. Some can be convinced to let people go if they are offered something nice or if they are entertained. (Though this brings to mind playing with your food…)
Explore carefully.
But in order to explore, main characters are going to need a winter coat. Don’t think a raincoat can be passed off as a winter coat either. The horses are too smart for that to work…
