Great for the plane of lost items or a cloud of lost items in the drift. Note that 20 will be something you are looking for.
0: A cursed item you thought you got rid of.
1: Piece of trash.
2: Front door keys for your home.
3: Childhood stuffed toy.
4: Prototype air rifle with 6 bullet clip.
5. An odd number of mismatched socks.
6. A jar full of marbles, which a past owner prominently labeled "Marbles" in the mistaken belief that it would prevent him losing them.
[#6 is based on a past GM's quirky taste in bathroom decor.]
