Lord Dane, I believe you have us confused with another order. While I do agree that the Teutonic Order does of course have the best look
, the order wasn't founded until the siege of Acre during the 3rd crusade (1190). We weren't even around until after Saladin took Jerusalem, though we did play a large part (along with the Templars and Hospitallers) in maintaining the crusader states throughout the 13th century.
Concerning our actions outside of the Holy Land (which I'm assuming is what you mean by "War-mongering") we actually had our theatre of operations changed to the Baltic in 1225, long before the end of the Crusades in the Holy Land. Our Baltic Crusades were legitimately called for and recognized by the papacy, and (in addition to converting the native peoples and bringing Christianity into the region) held a large monastic state comparable to any nation of Europe for a period of several centuries.
Furthermore, I would seriously doubt "Season of the Witch's" take on the Teutonic Order. The examples of battles shown had very little to do with the reality of the Teutonic situation. The Teutonic order operated in little to none of the areas mentioned during the time period, and weren't fighting Muslims at the time (the vast majority of the battles are depicted in the Middle East and fighting Muslims, while the Teutonic Order was in the Baltic battling pagans)
