As I've said before, the monk is one of my favorites. I've gone to some length to integrate them with my campaign world. I thought I'd show some of the more prominent fighting styles I came up with to illustrate what I want from the class and how it can be worked into D&D without "far-east" babble. This won't convince anyone, but it amuses me and I hope it amuses and inspires others:
Redhand: This unnarmed fighting style origates from diabolists and others who make pacts with the devils of the nine hells. The full extent of this mystical style can only be learned directly from summon devils, who demand consquitevely greater sacrifices for their tutorship from the practitioners. Yet, many find the sacrifice to be worth it, for the greatest users find thes can wreath their hands in hellfire and shatter the soul as much as the body with their strikes and kicks.
Magog: An orc combat style that is said to be older than the first weapons. Magog is a brutish style that focuses on fiststrikes and wrestling and looks at a low level like mere brawling. However, by excessive training and focus on the most primal parts of their mind, the user can shatter stone and throw giants. Practitioners are very much sought as bodyguards for their terrible intimidation potential, quick reaction and lacking need for weapons.
Monitor: To learn these forbitten techniques the user must travel deep into the underdark and live among its inhuman residents. At the high cost of loosing their sanities, the users bend the laws of reality at their touch, becomming a force to be recogned with. That is, if they can still remember their original purpose
Fatecutter: Used by secular phillosophers and cults concerned with fate, luck and doom, this style is only taught to carefully selected individuals, for it is said it's practitioners can reweave the strands of fate itself. It takes a lifelong dedication to mystic phillosophie and meditation, but a master kills his opponents by merely tipping them.
