The story of how I met the Witches of the Night is long and complex. To tell it in a way that everyone understands, I must explain the world that exists parallel to ours, which most people don't know exists. As such, I will start with what, for me, was the beginning: the event that made me aware of this world.

From a young age, I have been interested in urban exploration. At the age of thirteen, I joined the Braga urban explorers group and, over the years that followed, I explored the ruins of warehouses, factories, monasteries, and many other interesting buildings. But it was only in my thirties that I dared to do a solo exploration.

It was of a house in the parish of Palmeira, on the outskirts of Braga, that I had discovered during one of the many visits to the Dona Chica Palace that the group had organized. Although I drew attention to the house, no one else showed interest in exploring it. It was a small home, with just a ground floor, and with nothing to distinguish it from those that surrounded it. But something about it drew my interest. Perhaps because it reminded me of my great-grandmother's house, or because it was old enough to contain artifacts of the life of yore, not found in any modern house.

Whatever the reason, on a morose Sunday afternoon, when my wife went to visit her parents with our daughter, I drove to the old house. Taking care that the neighbors did not see me, I entered through a window whose glass and shutters had been broken by vandals.

On the other side, I found what was to be expected: a room full of broken glass, syringes and destroyed furniture. Anything of value had long been plundered. Still, I didn't give up. Carefully, fearing to find some squatter, I continued exploring the house.

I entered the corridor, which gave access to two more rooms. Passing over the remains of broken doors, I entered the bedroom, which didn't look any better than the living room. In the window, agitated by the wind, danced the remaining rags of crochet curtains. Clothes, from black dresses to felt hats, covered almost all the floor, clearly torn from the rotting closet and discarded for being worthless. Oddly enough, and despite the interest that antiquaries nowadays have in such furniture, an iron bed, with its white paint almost entirely replaced by rust, was still in the room, but upside down and tossed into a corner. The mattress had been removed and laid flat against the wall. It was covered in red, yellow, and white stains, and a shiver went up my spine as I thought of all that could have happened on it.

Then I went into the last room, the kitchen. The floor was littered with smashed crockery, and the cabinets were broken into and emptied. Everything else had been taken away.

Discouraged, I prepared to go back home. Unfortunately, there was nothing of interest in that house. The other urban explorers were right.

I was about to leave the kitchen when a metallic glow in the tiny pantry caught my eye. There, between broken shelves and nauseous remnants of rotten food, I found a door. The glow belonged to a primitive latch, which I opened immediately. On the other side, I found a stone staircase that descended into darkness. As I did when I explored a structure, I had a flashlight with me. Its light revealed a basement at the bottom of the stairs, apparently untouched by the vandals. Maybe the lack of daylight in there had kept them away.

Step by step, since I didn't know what awaited for me down there nor how robust were the stairs, I descended. At the bottom, I found a veritable time capsule from mid-century Portugal.

In one corner, I saw an old manual sewing machine, still with the cast iron pedal and the belt that transmitted the movement to the needle. In a table next to it, there was a charcoal iron. I could almost see smoke coming out of his little chimney.

On the other side of the basement, next to a rotting fabric sofa, I found a cabinet containing a tube radio, its yellowish plastic testament of its antiquity.

On top of all surfaces, there were testimonies of past times: oil lamps, slabs of slate, jars of ink, ink pens, etc. However, my gaze fell mainly on a wooden chest that lay on the floor beside the stairs. Curious, I opened it. It wasn't locked. Inside, I found albums with photographs, some of them certainly more than a hundred years old. It was sad to see those pictures of lively groups, couples dancing and dinner parties and thinking that most, if not all, of those people were gone.

Among the albums, however, I found a small notebook. I opened it and found that it was a diary. Normally, I never take anything from the places I explore, nor do I think that any urban explorer should do it, but having an account of the life of yesteryear was too tempting, and my curiosity got the better of me, as usual.

I left the house with the book in my pocket. I wanted to read it right there in the car, but dinner time was approaching.

When I got home, I put the book down and went to prepare the meal with the rest of my family. Despite being somewhat curious about its content, I dined calmly and even helped my daughter with her homework.

At last, I sat down at my desk and started reading. The stories in the diary were, in fact, interesting, fantastic, even, but in a way I didn't expect. They mentioned hidden places in cities, mountains, and even the sea, and encounters with fairies, vampires, witches, goblins and innumerable other mythological and imaginary beings.

Was it a work of fiction, or the reverie of a madman? At the time, I couldn't consider another hypothesis. But I also couldn't stop reading, because many of the stories were in or near places I knew.

When I finally went to bed, it was almost two in the morning, and I only did it because I had to work the next day. Still, with much effort, I was able to push the book away from my mind long enough to fall asleep.
