Princess of Georgia.... Or prince... Alternative timeline

To Siobnah! After death of great king David 4 the Builder of Georgia in 1125, what if his throne came in few years not to Demetre 1, his eldest son (Maybe he said that ruling Georgia is too hard for him), but to his imaginary second son - Nik, who before it prefered to either spend time with sisters Tamara and Kata, either with his great father. Well, David the 4 was great king, but nobles stayed the same. Their rebellions were not great cause of authority of Nika's father. Tries to rebel were crusheg by young king - maybe he prefers to wear dresses and act like woman, Mele (in Georgia word "Mele" meant both king and queen) Nika was like David - a just, sstrong, sometimes ruthless, but more kind ruler, who saved Georgia both from eager nobles inside and from strength outside - Bisantium, Cumans (Kiptchacks, Polovtsis), Turks-Seljuks and Crusaders. He or she was true heir of the great David. Writers said in chronicles that "The first bad new in this reign was death of Mele"
