And at the traditional Ars start date Mecklenburg is actually under the rule of the Danish king, Valdemar II. - if my memory serves me right this ended around 1225 - because the king and his son were ambushed and taken capture while hunting on the southern Danish island of Lyø by Henry of Schwerin, Henry the Black. Henry resisted the attacks to free the king and in the end the king had to accept defeat and acknowledge to to pay ransom for his release (money he propably already owed Henry but had not paid). This led to war between Denmark and Holstein, Mecklenburg and Pommern. These were all North German principalities that had been controlled by the Danish king, but unlike the rest of the German principalities the Danish king had denied recognising the German emperor, Frederic Barbarossa at that time, as his liege. On the 22. of July 1227 the forces clashed at a field in Holstein. The German princess led by Saxony and supported by the Hansa-cities (Lübeck, a hanseatic town were under Danish control and the Danish King was a thorn in their side bc of the control of the access ways into the Baltic Sea = taxes). The fighting was hard but in the end it was resoluted when one of the forces shifted alliance in the thick of the battle. As the dust and confusion settles the Danish king had to concede Holstein, Mecklenburg and Pommern, that from then on became part of Holy Roman Empire and ruled by German princes

Btw - the Danish conquest of the Southern and Eastern Baltic coast as well as the German colonization push eastward further inland were both called as crusades and given papal acknowledgment. Besides being a nominal thing, and the "rhetoric" of its time, this also influenced the creation of German Teutonic monastic knight orders and it is seen in architecture in the region. Even the present day flag of Denmark with its cross is clearly a crusader flag and originating from these events. Legends will have it that as Christian crusader forces, that included German monastic knights, were about to loose a large battle at Lyndanisse (present day Tallinn, Estonia) in June 1219 the flag came flying out of the sky. I is also said that as long as the Danish Archbishop Anders Sunesen held up his hands in prayer the Christians progressed, but when he got weary and his arms drifted downward they loosed terrain, resulting in people jumping to keep his arm held high rather then actually fight the enemy! A silly but curious detail – concerning the flag, the true story is more likely to be inspiration from the Johannites Knights. They also took part in this crusade and their flag looks suspiciously like the Danish – or rather the other way around.
Well, I’m loosing myself – back on track. The population on the Southern Baltic coast were the Wends, a Slavic people, and they had at their largest extent reached the Western end of the South Baltic coast. In 1043 they meet, with a force said to have been app. 15.000, the Danish-Norwegian king Magnus den Gode at Lyrskov in Jutland and were defeated. The Wends were significant not only because they were a non-christian people close to the christianized European heartlands – moreso because they had been christened several times but had turning back to their heathen Wendic faith. This and the fact that Wends on the 10th of November 1066 had sacrificed the head of bishop Johan of Mecklenburg to one of their gods known as Radegast (the one you find in RoP:I and probably the name that inspired Tolkien’s character of the same name), were probably additional factors in calling yet another crusade against the Wends. That their neighbours on top of this saw an opportunity for winning lands and loot, and putting a stop to the Wends notorious raiding expeditions, probably didn’t slow their responses. In the end the Saxons, well aided by the Danish, all but obliterated Wendic culture. One of the famous chapters from this story is the conquest of the island of Rügen (home of Crintera) and Arkona – the last stronghold of the Wends – by the Danish king in 1169 (it had also been invaded in 1136 and the people christened by force, at least until the fleet had sailed back home..). The four-faced idol of the Wendic god Svantevit (“I see the Worldâ€) was toppled and dragged out of town. The Wendic crusade seemingly at end, and churches were build across Rügen to make sure that the Wends would this time stay Christian...
So basically the Baltic coast is in the early 13th century an area characterized by recent conquests, heathenry and crusade - a great place for infernalism and horrible intrigue! I reckon this also inspired the entry in RoP:I about infernalists in the area – and while it is great, I also enjoy going further and look at primary sources too. I am certain that you can find more inspiration in the GoF on Arkona and Svantevit. On the internet you can find several references to the other Wendic gods. If you want to know more about the conquest of Rügen, and since I know you Ferretz can probably read Danish, I would recommend Saxo Grammaticus’ “Gesta Danorumâ€. It was written by the scribe Saxo (best know for having inspired Shakespeare's Hamlet) who was ordered by the bishop Absalon to write the history of the Danes – and as such it is filled with glorifications of his employer(s) and tall tales of old legends. But it was written in the early 13th century, so it is close to the events, and the tone is in-setting which might inspire as well. His 14th book is about the conquest and you can find it here.
