"Battles leave empty thrones, my son. Your grandfather, Karl vor Hornberg, was a commoner, and a sell-sword, with only two men under his command: His brothers. By the Battle of Witges he commanded a platoon, and the Duke awarded him the now-vacant knighthood of the recently deceased traitor family von Kleist. By the time I took over the company, we had three battalions and a barony. For my support in the Battle of Keldbrukke, His Majesty, King Jerger awarded me the recently vacated Duchy of Beidebaum. You now take command of the greatest army west of the Neiße river. See to it that your son is called King."
- Kristof von Hornberg to his son, Ulrich von Hornberg, on the occasion of his 18th birthday.
Recruiting vassals is one of the keys to winning Lyssan. A vassal is an influence card representing an alliance with a powerful faction within the Empire. The von Hornbergs are one of these: a noble family that built their power a gallon of blood at a time, working their way up through the gentry by fighting in every major battle and having a knack for choosing the winning side.
Vassals give a player an immediate influx of units, and the ability to hire more agents of a type than they would normally be allowed. In a game were the final victory point can come from fielding the most knights or priests or spies, this can make the difference between winning and losing!
Only one can't depend on vassals. The alliance with the vassal is a 'holding', and holdings can be stolen by enemy spies, given the chance. When a vassal card moves from one player to another, the agents from the vassal also swap sides!
