The result of Kai-khosráu's expedition against the enchanted castle, compared with that of Fríburz, was sufficient of itself to establish the former in the king's estimation, and accordingly it was announced to the princes and nobles and warriors of the land, that he should succeed to the throne, and be crowned on a fortunate day. A short time afterwards the coronation took place with great pomp and splendor; and Khosráu conducted himself towards men of every rank and station with such perfect kindness and benevolence, that he gained the affections of all and never failed daily to pay a visit to his grandfather Káús, and to familiarize himself with the affairs of the kingdom which he was destined to govern.
Justice he spread with equal hand, Rooting oppression from the land; And every desert, wood, and wild, With early cultivation smiled; And every plain, with verdure clad, And every Persian heart was glad.
The tidings of Khosráu's accession to the throne were received at Sístán by Zál and Rustem with heartfelt pleasure, and they forthwith hastened to court with rich presents, to pay him their homage, and congratulate him on the occasion of his elevation. The heroes were met on the road with suitable honors, and Khosráu embracing Rustem affectionately, lost no time in asking for his assistance in taking vengeance for the death of Saiáwush. The request was no sooner made than granted, and the champion having delivered his presents, then proceeded with his father Zál to wait upon Káús, who prepared a royal banquet, and entertained Khosráu and them in the most sumptuous manner. It was there agreed to march a large army against Afrásiyáb; and all the warriors zealously came forward with their best services, except Zál, who on account of his age requested to remain tranquilly in his own province. Khosráu said to Káús:
"The throne can yield no happiness for me, Nor can I sleep the sleep of health and joy Till I have been revenged on that destroyer. The tyrant of Túrán; to please the spirit Of my poor butchered father."
Káús, on delivering over to him the imperial army, made him acquainted with the character and merits of every individual of importance. He appointed Fríburz, and a hundred warriors, who were the prince's friends and relatives, to situations of trust and command, and Tús was among them. Gúdarz and his seventy-eight sons and grandsons were placed on the right, and Gustahem, the brother of Tús, with an immense levy on the left. There were also close to Khosráu's person, in the centre of the hosts, thirty-three warriors of the race of Poshang, and a separate guard under Byzun.
