Hey brothers I wrote some rules to run Black Dragons as a Chapter. This is just a beta rule set and doesn't include some stuff. Let me know thoughts.

It could use some polishing IMO, but overall a great write-up

Very nice, although there's a good bit more to add: Psychic powers, chapter relics, and some unique talents relating to their mutation. I'd be happy to help out, if you like.

It's not my project, but by all means, do so - I always like to see smaller, more obscure Chapters getting some love, so keep 'em coming. Especially if you have some Dark Hunters material lying around - with the legal quagmire around the name, we won't see official releases in the next few decades, I'm afraid.
