It is a well-known thaumaturgical fact that a power focus works best when it contains a piece of the thing over which one desires power.
It is with great pride, therefore, that we present our most powerful artifact to date: the Dragoncaller Ring.
The ring is sterling silver, brightly polished or malevolently blackened per your desire, displaying and protecting a translucent agate webbed with dragon veins. Each is unique; each may be used to call a different dragon, wyvern, wyrm, flying newt or similar. Sadly, we are not able to tell you which stone will call which dragon, due to a strange fire in the Vault of Codexes in which we house such records. Use, therefore, at your own risk.
