When Passionless Valley was first introduced in the middle of ROCH, the place and associated wulin subcommunity had not previously been mentioned. We know for sure that the Kau siblings of the Iron Palm Union knew of its existence (because sister Kau Cheen Chek had married into the Gung Sheun Family of Passionless Valley), but did the cognoscenti of greater wulin (e.g. the Greats, the Cheun Jen Sect Elders, etc.) have any idea that such a place and organization existed before Yeung Gor, etc., visited it?
