Magicians of Xanth - Bink

Served as king pro-tem during Trent's reign.

The Magician of Magical Invulnerability, Bink was the main character in the first two novels, A Spell for Chameleon and The Source of Magic. He is the son of Roland of the High Council and Bianca. Later in the series, he makes a rejuvenated appearance in Zombie Lover. The later books are taken over by his magician-caliber family members.

At one point he gets banished for not possessing a magic talent. To prevent the exposure of its existence, his talent prefers to work in roundabout ways, at one time making an invisible giant walk by to stop him from revealing his talent while under a truth spell, for example. If the exact nature of his talent were known, then he would be vulnerable to those who want to attack him through non-magic means - thus making (his own) magic the indirect cause of his injury. So his talent is kept hidden by the select few who know it. It also makes him a lucky man in a series of rather bizarre and dangerous coincidences (almost breaking his ankle after tripping on a rock to escape from the Gap Dragon).
