Krozair of Kregen is a science fiction novel written by Kenneth Bulmer under the pseudonym of Alan Burt Akers.

[1] The book directly follows Renegade of Kregen with Prescot being made an oar slave on a Magdagian galley and still trying to come to terms with the death of his daughter Velia.

When Vax gets drunk celebrating their new freedom he reveals that he is Jaidur of Valka, youngest son of Pur Dray, who he hates for abandoning his mother and ruining his chances becoming a Krozair.

Eventually, to prevent Vax from going to Magdag, Prescot breaks the news to him that his sister Velia has been killed, without disclosing the fact that he is his father and knows of his true identity.

Traveling east Prescot and his men learn that Zandikar is under siege, that the City's King has been slain and a usurper holds the throne.

Prescot realizes the siege has come to a decisive stage when King Genod arrives with an armada of flying boats and saddle birds, against which Zandikar is defenseless.

After reaching the coast near the enemy positions Prescot leaves his men and enters the Grodnim camp, again assuming the alias of Gadak.

He meets Grogor and through him gains access to Gafard and King Genod and manages to enter their flying boat for a reconnaissance mission.

Gafard is surprised to see Gadak again, and finally, when Prescot adds the pieces together for him, recognizes the latter is Pur Dray and the father of his late beloved wife.

The final assault of the Grodnim against Zandikar with flying boats pushes the defenders close to defeat with a gate falling when an air armada from Valka led by Delia takes the day and destroys the besieging army.
