Tomjon is a character in the novel Wyrd Sisters. He is the son of the Queen of Lancre and is the rightful heir to the throne of Lancre. He was delivered by midwife Nanny Ogg, to whom the late queen confided the true identity of the father of the baby. It is assumed that the father of both he and his half - brother Verance is not the king but a famous court Fool in the Guild of Fools and Joculators. When King Verence I of Lancre is murdered by his cousin, Duke Felmet, the King's crown and the baby are given to the Lancre witches for safety. The witches hand the crown and the child to a troupe of traveling actors in the travelling troupe of Olwyn Vitoller. They each gave him a blessing, as was the tradition:
- (Magrat Garlick): "He will make friends easily". (Something she-herself never been able to get the hang of.)
- (Nanny Ogg): "A bloody good memory is what he ought to have. He'll always remember the words".
- (Granny Weatherwax): "Let him be whoever he thinks he is. That's all anybody could hope for in this world".
They acknowledge that destiny will eventually take its course and baby Tomjon will grow up to defeat Duke Felmet. He is raised not knowing his parentage and becomes a very accomplished actor. He remembers all the words to all the plays written by the dwarven master playwright Hwel, thanks to the interference of the witches, and can bring tears to the eyes of the toughest audience - including bandits that waylaid them, dwarves mid-riot and even the folk of Lancre and the Sto Plains. He can become anybody before your eyes - from Death himself, to an old man, to a simpering wench. In short, he is the most talented artiste the Disc has ever seen. His talent makes it possible for Olwyn Vittoler to build The Dysk in Ankh-Morpork - the Discworld equivalent of of London's Globe. In the end he decides to remain an actor and passes the crown to his half-brother Verence II.
