Time of the Twins is a 1986 fantasy novel in the Dragonlance series by American writers Margaret Weis and Tracy Hickman.

The book opens with a meeting between the devout cleric, Crysania, the historian, Astinus, and the dark mage, Raistlin.

After detailing the meeting between Crysania, Raistlin, and Astinus, the book shifts to the character Riverwind arriving at the Inn of the Last Home in Solace.

Later, Tika casts Caramon out of the house to accompany Tas, Crysania, and Bupu (a gully dwarf who fell in love with Raistlin), who are travelling to the Tower of Wayreth.

En route, they encounter Lord Soth, a death knight, who would have killed Crysania had not Paladine interceded and brought her soul to dwell with him.

The group continues on to the Tower where they find out Raistlin plans to travel back in time and gain power to challenge Takhisis, head god of evil, and take her place.

The group finds themselves in pre-Cataclysm Istar, a holy empire and residence of the Kingpriest, the most powerful cleric in the world.

Thanks to Raistlin's intercession, guards discover them and they think that Caramon has attacked Crysania, as he is dressed in rags and she is covered in blood.

Crysania is taken to the Temple of Paladine, home of the Kingpriest, and Caramon is taken to the Games of Istar, a colosseum-like arena which pits contestants against each other in mock fights.

Tas, with the magical time travelling device, goes to the chamber where the Kingpriest will make his demand of the gods for great power in order to defeat evil.
