The brooch was obviously magical, yet had mysterious properties. One such property was that the magic of the brooch could in no way be canceled or dispelled. Gromph had frequently erected anti-magic shells around himself yet continued to remain young via the magic of the brooch. Also, the brooch had no effect on a child of any race if worn. The magic somehow attuned itself to whatever race wore it, and the magic would not take effect unless it sensed that the wearer was above a certain age. Obviously, much more study was required to understand the full characteristics of the brooch of perpetual youth.
