L5R: Hammer and Flame
The L5R Wiki provides a lot of useful information. It is not always correct but as a footnoting source for other areas, it is wonderful. A good starting point to work out from to learn more.
Kaze no Shiro is a wonderful website that collects all the fiction and history of Rokugan in one handy location. Reading through the Samurai arc fiction provides a good basis to where we are beginning.
The Kuroiban’s file section hosts some very useful material. Character sheets, cheat sheets, the SUP and maps. If you are looing for something that may be the place. Their forums are not heavily used but if you have any RP questions related to the Scorpion they may be the place to go if I don’t know an answer.
