Adventure mid summer nights dream

I was thinking of adapting this for my Rhine game. Does anyone have suggestions on possibly replacing the Albigensian Crusade? I was thinking of just extending some of it into Germany but I'm looking for alternate idea's and suggestions.

Place it in Pomerania (bonus: a land known for wolves and werewolves), and use the Baltic crusades instead.

Good idea I could possibly extend that into the Rhine gorge where I'm running it.

You can also place it in lower Rhine valley or in Saxony where catharism was strong even if their eradication was less violent that in languedoc.
