Unbeknown to Jon the stranger left the legendary Grellstone, a mysterious artifact capable of altering reality and granting virtually any wish ... providing the person doing the wishing is angry. The greater the fury, the more powerful the magic. Just being mildly irked might result in incomplete or temporary wishes being granted. Not really angry at all? The Grellstone probably won't do anything then... but who knows? Magic is a strange and fickle beast.
