Interesting Times: The Play is a new stage adaptation of one of Pratchett's best-selling novels. The Discworld's most inept wizard, Rincewind, has been sent from Unseen University in Ankh-Morpork to the oppressive Agatean Empire to help some well-intentioned rebels overthrow the Emperor.

He's assisted by toy-rabbit-wielding rebels, an army of terracotta warriors, a tax gatherer, and a group of seven very elderly barbarian heroes led by Cohen the Barbarian. Opposing him, though, is the evil and manipulative Lord Hong and his army of 750,000 men.

Rincewind is also aided by Twoflower—Discworld's first tourist and the author of a subversive book about his visit to Ankh-Morpork, which has inspired the rebels in their struggle for freedom. The book is called What I Did On My Holidays.

When last seen, the singularly inept wizard Rincewind had fallen off the edge of the world. Now magically, he's turned up again, and this time he's brought the Luggage.

But that's not all...

Once upon a time, there was an eighth son of an eighth son who was, of course, a wizard. As if that wasn't complicated enough, said wizard then had seven sons. And then he had an eighth son — a wizard squared (that's all the math, really). Who of course, was a source of magic — a sourcerer.
