I don’t want to play anymore. All it does is make you care too much. The more you care, the more you have to lose.
Witches and wizards often reveal themselves to each other in public by wearing purple or green, often in combination. In Britain (and much of Europe) purple has an association with both royalty and religion. Purple dyes, being costly, were once worn only by those who could afford them; bishops’ rings are traditionally set with amethysts. Green has long had a supernatural connection in the UK. Superstition says that it ought to be worn with care; the fairies are supposedly possessive of it, as it is their proper colour. It ought never to be worn at weddings, due to a further association with misfortune and death. Green is the colour of much ‘Dark’ magic; of the ‘Dark Mark’, of the luminescent potion in which Voldemort conceals one of his Horcruxes, of many ‘Dark’ spells and curses, and of Slytherin house. The combination of purple and green, therefore, is suggestive of both sides of magic: the noble and the ignoble, the helpful and the destructive.
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.
"Gingerly Harry took another step forward. Something shifted in the shadows at the end of the hall, and before any of them could say another word, a figure had risen up out of the carpet, tall, dust-colored, and terrible; Hermione screamed and so did Mrs. Black, her curtains flying open; the gray figure was gliding toward them, faster and faster, its waist-length hair and beard streaming behind it, its face sunken, fleshless, with empty eye sockets: Horribly familiar, dreadfully altered, it raised a wasted arm, pointing at Harry."
