Talisman
Mages often create magical items to aid them, either by providing some sort of protection from harm or simply by granting convenient niceties. Sometimes, mentors also pass along potent magical artifacts to their students. The Talisman Background indicates that the character owns and knows how to use such an item.
The character probably doesn't know how to create more items of the same kind; perhaps the one he has was the result of magical fluke or a celestial conjunction that happens once in a century, or perhaps (as suggested) the Talisman was a gift. All magical items are special, however, and simply churning them out robs them of their dramatic impact.
Chapter Six has examples of various kinds of Talismans. The Storyteller should use those items as measuring sticks for any that the players may wish their characters to own. The highest Pillar level used to make a Talisman (no matter how many Pillars are used) determines the Talisman's level.
