Fantasy books, stories, ＆c

I stumbled upon this story ages ago and I can't remember the name of the website anymore. It was a collection of fantasy stories taking place in the same world written by two people. The story I started reading starts with a man waking up in a field with a dagger wrapped in silk laying on his chest. When he looks around he sees other people laying in the field as well with similar bundles on their chests. He gets up and walks to a nearby tree row. As he is looking in the trees someone else comes to tell him that the others are waking up too. As they start talking and forming small groups a wizard appeared and announced to everyone that "the trial" was beginning. A large tower had also appeared behind him. The people were then teleported into a dark room that was presumably inside the tower. The people started calling out to each other and fumbling around in the dark and that's where I stopped reading. I was really excited to read those stories because it seemed like there would be a lot of world building. I would very much appreciate any help finding the story or the website it was on.
