This setting is fantastic! I'm about to start a game in this world here soon and I'll update more after it has seen some table time but here are the best selling points:
the lore is easy to grasp, espeically if you are familiar with the dark ages in Europe
the themes are darker and more gritty than the standard RoT setting
FANTASTIC and memorable enemies to challenge your players
options to run all human monster hunters or an all monster group
an open world to place your own towns and locations in
