 Voyk was born in Wallachia , according to the nearly contemporaneous historians Johannes de Thurocz and Gáspár Heltai . Voyk had been serving as a " court knight " in the royal court when he received the demesne of Hunyad from King Sigismund , suggesting that he was descended from a prominent Wallachian family . Modern historian , Kubinyi , wrote that Voyk most probably joined Sigismund in 1395 . In this year , Sigismund invaded Wallachia and restored his vassal , Mircea the Old to the princely throne .
