Jobst was an ambitious and versatile ruler, who in the early 15th century dominated the ongoing struggles within the Luxembourg dynasty and around the German throne.

Jobst was presumably born in 1354 in the Moravian residence of Brno, the eldest legitimate son of Margrave John Henry, younger brother of Emperor Charles IV.

[2] Designated heir upon his father's death in 1375, he ruled the Margraviate of Moravia, and would often quarrel with his younger brother Prokop and the Bishops of Olomouc.

In 1388, Jobst received the Duchy of Luxembourg, given in pawn by his cousin King Wenceslaus, son of the late Emperor Charles IV.

In the game, he is shown with Divish of Talmberg, Hans Capon, Hanush of Leipa, John II of Liechtenstein, and Radzig Kobyla planning on how to defeat Sigismund and free Wenceslaus from captivity.
