The Twins' Secret

Septem Numina is a magical and ancient town, hidden in the folds of an eternal time. To find it, we should travel between plateus and Norwegian cliffs, through flowery valleys, between fields and bays from the ocean.
In the town it lives magical creatures and human beings, but it's hard to tell ones from the others. In fact, spirit animals, wizards, witches and normal citizens have been living in their stone houses for so long now, that nobody pays attentions to their rarities. And after so long, they're all a bit alike! Except spirit animals, who are very, very illuminated and ghosty, and look like forest animals! Wizards and witches of the valley call them so they can take care of the youngest ones in town.
This story is told, precisely, by one of them: Niestgou, the spirit animal of the twins Leo and Bellatrix.
