at your choice

You're from a modern world, and as you walk down the street, you catch a glimpse of an antique shop that seems to have never been there before, since you often pass by on your way home. Anyway, you enter the shop and are greeted by a short, hunched-over woman with glasses. She asks what you're here for, and you simply stare in fascination at the strange objects on a shelf. A particular circular object catches your eye, and the woman warns you not to get too close, but you ignore her. The closer you get, the brighter the object shines until you touch it, and a light appears. And there you are, in a strange, medieval fantasy world full of races: orcs, fairies, dwarves, mermaids, and so on. ( *This is my first time doing this; I hope you like it* .)
