Blossoms need BW?

[Rodolfo]

Hi there. I want to know if, similarly to mouseguard, the blossoms game is self contained.

I mean... if with only this book i have all material (from full rules to flavor) to play the game.

(Unfortunately my BW copy has gone missing in the postal office of nowhere, should've arrived weeks ago :()

You need BWR to play Blossoms.

Thanks!

I'll see myself to the system first then
