I'm impressed, very impressed by the sheer scope of this Homebrew Project, and the amount of love and effort that seems to be going into it. Taking over 200+ Homebrew Disciplines, as well as who knows how many different classes and prestige classes, and condensing them down into a smaller, more internally balanced, and jointly flavoured homebrew splatbook is a massive undertaking. Though I think it might need to take more than 1 'splatbook' to cover all of the potential material at the end of the day!

Especially as... well. I would be remiss not to kindly point you towards a collection of Homebrew that includes my favourite Martial Disciplines to this date, as well as a collection of Martial Adept classes. Among other things. They aren't part of the Homebrew Discipline compendium, but a lot of them are very favourable and have very fun, unique mechanics to them as well. I would be estastic in seeing them getting more love and attention.
