yes, that is what happens, the conversation branches off from the original topic into to other topics,
but the question WE have been asking is if narrative of a species can effect gameplay at what point does that 'narrative' influence things enough to become 'mechanic'?
that's the point, the narrative of the triton is that they're a fishman who lives underwater, the mechanics say standard creatures cannot breathe underwater, so if no species mechanics exist how do you square that circle? other than with a fishman who can drown.
