Tannberg has a few differences to your normal

-campaign, not alone for the Gunpowder used:
It's a sinister country, filled with horrible creatures that stalk the dark woods and lost valleys. At the Northwest the Northmen plunder the coast and have their own occupied piece of land, while in the capitol Tannstadt the Crown, the Church and the Inquisition intrigue and silencly battle against each other for supremacy - meanwhile the shadows of the night grow and stretch their fingers toward civilisation.
Players start as members of the Inquisition and pick special templates which equip their characters with the appropiate trappings they need - fighters normally pickup the "Kreuzritter", while Scouts tend to the Witchhunters, which are also ersponsible for the formal acts of exorzisms.
Spellcasters have a special role - Tannberg is very low magic - so wizards and (still not unmasekd) blackmages have a guildlicense from Billstein to cast (but are still observed) while the healers are members of the Church'S Priesthood with their own opinion about the Inquisition and their own motivations.
The Inquisitiors aren't the typical badwithchunterboys: Yes , of course they are cruel guys and villagers are afraid in their presence - but the darkness is strong in Tannberg, truly - so the Inquisition is really needed out there in the small hamlets and backside villages, to hunt down heretics, witches, undead, werecreatures and other horrors, while the Northmen set the coast at flame and intrigues eat civilisation's roots.
