When Manuchehr arrived with the army of Iran, Salm had a champion waiting. This was Kakui, of Zahhak's blood, who had come out of his fortress to stand against the house of Fereydun.

The two fought from morning until the sun was low. In the end Manuchehr seized him by the belt and pulled him from the saddle. The game paints Kakui with a snake on his helmet, so that nobody forgets whose grandson he is.
