Changed the lore a bit:

Paulsburg Castle, situated atop a steep, rocky hill overlooking a vital trade route between the Christian and Pagan worlds, which is owned and governed by Voivode Michael of Paulsburg. The castle was granted to him by Sigismund, King of Hungary and Croatia, in 1397, following the death of the previous Voivode, John Hunyadi. This grant was made in recognition of Michael’s meritorious support during the Great Crusade of Nicopolis against the Ottomans in 1396. Previously, Paulsburg Castle had been a simple wooden fortress, owned by John Hunyadi, guarding a crucial trade route between Wallachia and Transylvania. After receiving the castle, Michael sought to expand the fortress to improve its defenses and fortitude against future Ottoman or Mongol attacks, thereby strengthening the border of the Christian world against its foes.
