First, to Ronald Bilius Weasley. I leave my Deluminator, a device of my own making in the hope that, when things seem most dark, it will show him the light.
To Hermione Jean Granger. I leave my copy of The Tales of Beedle the Bard in the hope that she find it entertaining and instructive.
To Harry James Potter. I leave the Snitch he caught in his first Quidditch match at Hogwarts as a reminder of the rewards of perseverance and skill.
