Here is version 0.2b of Brother Bear, Sister Wolf. This update fills in a lot of gaps and changes a few rules based on playtest experience. Changes include:

• Expanded system for establishing important aspects of the world during game setup.
• Updated journey system.
• Changed advancement for PCs.
• Fortune rolls. 
• Info on creating animal NPCs, with examples.
• Info on creating spirits, with examples.
• Examples of play added where that would help in learning the system. 
• More info for the GM on how to set up and run the game, with examples of starting situations. 
• Improved reference sheets. 
• Probably other things I don't remember changing, but are still good.
