The Widow of Roses is a sketch of a campaign with interesting characters and plots, presented in very attractive layout, with an expressive and eye-catching art direction.

I would definitely see hacking this into a setting/campaign for Band of Blades, whether that is opposing the Widow, or serving her. But in most other fantasy adventure games this could be the basis for a pretty good arc.

Definitely recommended for someone who would use this as a framework, but this probably isn't for you if you want something table ready.
