Giv (Shahnameh)
Kay Khosrow is one of the greatest kings of Shahnameh and he is the son of Siavash and Farangis and the grandson of Kay Kavus. Kay Khosrow was born and grown up in Turan. One day the Soroush (angel) comes to Goudarz in his dream and tells him that the son of Siavash is in Turan and Iranians should go there and bring him back to Iran. He tells Goudarz that only his son, Giv, could do this job. Goudarz then sends Giv to Turan in search of Kay Khosrow and after seven years, Giv finally finds Kay Khosrow and brings him back to Iran. Giv along with most of other Iranian heroes, disappears in snow during Kay Khosrow's ascent, because they don't have Farr-e Izadi (a divine force).
