Challenge: Deluminator
Word Count: 100
Excerpt from a letter to Severus Snape, written by Albus Dumbledore prior to his death:
...I also entrust to you the prototype for my Deluminator. The final product is intended to go to Ronald Weasley, as I foresee that he will need its mastery over light, but I believe that the prototype will be best in the hands of that rarest of creatures, a wizard with a logical mind.
Please do not hesitate to work with it. As I said, this is but the prototype, so there is much that can be improved to assist you in the coming months....
